Other Resolved Issues

Java Applets

Radar #4216053

LiveConnect and Dialogs

Description:

Attempting to show a dialog, like a FileDialog, using LiveConnect caused a deadlock that could hang the host application.

Resolution:

Showing a dialog via LiveConnect no longer causes a deadlock.

Java Aqua Look and Feel

Radar #4266079

JProgressBar Prevents Application Exit

Description:

The animation timer used in painting the Aqua progress bar did not stop when the progress bar was hidden. This could prevent the component from disposing.

Resolution:

The animation timer is now halted, allowing for proper component disposal.

Java AWT

Radar #4008177

MouseInfo.getNumberOfButtons() Return Values

Description:

The method MouseInfo.getNumberOfButtons() always returned a value of 0, regardless of the number of buttons on the mouse attached to the system.

Resolution:

The correct number of mouse buttons are now returned. If no mouse is attached, -1 is returned.

Radar #4156678

Headless Applications and AWT

Description:

In a headless application, trying to use any AWT class caused a debugging message to be printed, halting the application while waiting for user input.

Resolution:

The debugging message no longer appears, allowing the application to continue executing.

Radar #4160457

Pasteboard Keyboard Shortcuts and Swing Applets

Description:

Swing applets weren't receiving copy, cut, and paste events that were the result of a keyboard shortcut (Command-C, Command-X, and Command-V, respectively).

Resolution:

The keyboard shortcuts for Pasteboard operations now function as expected. Note that Swing applets have their own pasteboards that are not shared with the system's general pasteboard.

Radar #4164891

Window Memory Leak

Description:

Some Window and Window subclass objects leaked memory.

Resolution:

Disposed Windows no longer leak memory.

Radar #4175954

Robot.createScreenCapture Crash

Description:

Calling Robot.createScreenCapture() with invalid bounds (larger than the actual display) caused the application to crash or the return a corrupted image.

Resolution:

The application no longer crashes. Values outside of the display are black in the returned image.

Radar #4201970

Nested Modal Dialogs

Description:

Nested modal dialogs don't behave properly if they all use a common parent. For instance, a focused Dialog may end up behind an unfocused Dialog.

Resolution:

Nested modal Dialogs maintain their ordering.

Radar #4247594

Graphical Java applications and Case-sensitive Filesystems

Description:

On case-sensitive filesystems, like UFS, Java applications that try to show a user interface failed to launch.

Resolution:

Graphical Java applications launch normally on all filesystems.

Java Events

Radar #4086462

Malformed MouseEvents

Description:

When the Command key is held down, a MouseEvent sometimes had an incorrect source Component. When the Command key was held down, a MouseEvent sometimes reported that the third mouse button was down when it was not. When the Command key was held down, MOUSE_CLICKED events were not delivered to unfocused Components. When the Shift key was held down, a MouseEvent sometimes reported that the first mouse button was down when it was not.

Resolution:

MouseEvents are no longer malformed when Command or Shift are held down.

Radar #4176668

Robot Mouse Events

Description:

Because Robot was set to take precedence over genuine user events, posting a mousePress without later posting a mouseRelease caused the entire user interface to stop responding to mouse clicks.

Resolution:

Robot events no longer take precedence over genuine user events.

Radar #4237416

Custom DataFlavors Across Separate Virtual Machines

Description:

If a Java process defined a custom DataFlavor, other Java processes could not read data stored within that DataFlavor.

Resolution:

A custom DataFlavor is now read properly by the general system clipboard.

Radar #4238470

Images on the System Pasteboard

Description:

When an image was copied to the general system pasteboard, the image was corrupted.

Resolution:

The image is no longer corrupted.

Java Libraries

Radar #4084603

JMX and jconsole Fixes

Description:

The management.properties file wasn't available on J2SE 5.0 Release 1, disabling JMX features.

Resolution:

The management.properties file is available with this release. To work with JMX, jconsole has been updated to connect correctly to the virtual machine.

Radar #4116981

Compile Failure with .zip or .jar File Extensions

Description:

If the classpath had entries that pointed to files without .zip or .jar extensions, javac issued a warning about the file and refused to compile the executable. This bug is found in Sun's bug database as Bug ID 6295519.

Resolution:

javac ignores invalid files with .zip and .jar extensions.

Radar #4149837

Reopening Files with java.io.RandomAccessFile

Description:

When a file was created with rw permissions and then shortly thereafter a new RandomAccessFile object was instantiated for the same file in rws mode, a FileNotFoundException (File Exists) exception is thrown.

Resolution:

RandomAccessFile no longer throws an exception in this case.

Java Networking

Radar #4236458

Reusing Addresses with DatagramChannels

Description:

Calling setReuseAddress() on a DatagramChannel did not have any effect.

Resolution:

Calling setReuseAddress() now reuses the address.

Java Printing

Radar #4093580

Using Multiple Printers

Description:

Print jobs were often printed to the default printer instead of the selected printer.

Resolution:

A targeted printer prints the document, as expected.

Java Swing

Radar #4134772

Swapping Menu Bars Within the Screen Menu Bar

Description:

When an application used the screen menu bar and swapped between multiple menu bars via setJMenuBar, duplicate menus were shown.

Resolution:

Duplicate menus are no longer shown.

Java SWT Support

Radar #4091298

SWT Applications Using AWT Classes

Description:

Using an AWT class within a SWT application is normally not possible, due to issues with threading during the startup of the AWT. One workaround was to set the -Djava.awt.headless flag equal to true at runtime.

Resolution:

AWT startup detects the existence of the SWT and sets up AWT in headless mode automatically. Using the -Djava.awt.headless is no longer necessary.

Java Text

Radar #4122177

Distorted Text Layout Bound Values

Description:

The bounds returned by java.awt.font.TextLayout.getBounds() were inaccurate.

Resolution:

Returned values are more accurate.

Radar #4164128

Incorrect FontMetrics in a Scaled Graphics2D Object

Description:

When a Graphics2D object was scaled using its scale method, the text dimensions as reported by a FontMetrics object were incorrect.

Resolution:

The reported text dimensions are now correct.

Radar #4176164

Transformed Strings

Description:

Scaled or rotated strings were drawn with incorrect spacing between the letters, doubly transformed glyphs, or glyphs scaled non-proportionally.

Resolution:

Scaled and rotated strings now draw correctly.

Radar #4156757

Display Issues after Character Set Change

Description:

Changing the input source character set wasn't immediately respected by input fields.

Resolution:

Input source character set changes take effect immediately.

Java Virtual Machine

Radar #3499564

JVM Stat Tools

Description:

The jvmstat tools were not available with J2SE 5.0 Release 1.

Resolution:

/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/jps

Prints the process ID (<pid>) for all active Java processes

/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/jinfo -flags <pid>

Prints a histogram of Java object heap for the specified process

/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/jmap -permstat <pid>

Java Web Start

Radar #4074412

Ignored Descriptor Elements

Description:

Java Cache Viewer didn't support JNLP documents that had an "association" element in their "information" descriptor. The application worked as desired, but any declared associations were not registered with Launch Services when the user created a desktop application.

Resolution:

An application's "association" element is registered properly.

Radar #4088809

Saving Web Start Applications as Local Applications

Description:

Launching a local JNLP application after it was modified caused the Save dialog to appear again.

Resolution:

Updated applications no longer need to be saved again.

Radar #4126743

Creating Local Applications with Java Cache Viewer

Description:

Java Cache Viewer created local applications that always tried to launch in Java 1.3.1 or would not launch at all.

Workaround:

Java Cache Viewer creates correctly formed desktop applications
