Java Applets

Radar #4889300

Default applet memory limits too low

Description:

The default maximum heap size for Java applets was set to 64 MB in Java 1.4.2 and J2SE 5.0. This is inconsistent with other platforms and often not enough for memory-hungry applets.

Resolution:

The default maximum heap size for applets is now 96 MB in Java 1.4.2 and J2SE 5.0.

Java Application Support

Radar #4600115

Previous Java application stub incompatibilities

Description:

The Java application stub shipped with J2SE 5.0 Release 4 and various Intel-based Macs requires Mac OS X 10.3.9 or later to run.

Resolution:

A new Java application stub is included with Java for Mac OS X v10.4 Release 5. This stub is Universal (supports both PowerPC and Intel-based Macs) and is compatible with Mac OS X v10.2 and later for Java 1.4.2 applications. This stub also fixes launch issues on Mac OS X v10.3 with QuickTime 7.0.4 and later installed. To use the latest stub, either repackage your application with Jar Bundler or swap your application’s stub with the one found in /System/Library/Frameworks/JavaVM.framework/Resources/MacOS/.

Java AWT

Radar #4733011

Transparent window dragging

Description:

Window made transparent via setBackgroundColor couldn’t be dragged.

Resolution:

Use a boolean value with the apple.awt.draggableWindowBackground per-window client property to control if a window can be moved by dragging its background.

Java Events

Radar #4536860

Dead keys reported incorrectly

Description:

Dead key combinations, such as Option-E and Option-U, were reported as a key event with no key code or key character.

Resolution:

Pressing a dead key combination generates the correct code, such as VK_DEAD_GRAVE, VK_DEAD_ACUTE, or VK_DEAD_CIRCUMFLEX, for that combination.

Java Graphics

Radar #4737115

Incorrect synchronization

Description:

A race condition in the clean-up of drawable delegates for native peers could result in a crash.

Resolution:

The clean-up of drawable delegates for native peers is now synchronized correctly.

Java Input Methods

Radar #4527629

Erroneous Input Method Events

Description:

Components that were not prepared to respond to input method events received them, which caused the AWT to bring up an input window.

Resolution:

Components that return null from the getInputMethodRequests method no longer receive input method events.

Radar #4693179

Multiple characters generated by one key stroke

Description:

If a component didn't support input method events and a key combination resulting in multiple characters was entered, the component only received one KEY_TYPED event for the first character generated by the event.

Resolution:

Entering a key combination that results in multiple characters now generates a KEY_TYPED event for each character generated.

Java Libraries

Radar #4801241

Daylight Saving Time adjustment

Description:

Beginning in 2007, Daylight Saving Time in the United States starts three weeks earlier (March 11, 2007) and ends one week later (November 4, 2007).

Resolution:

Java for Mac OS X v.10.4 Release 5 includes new time zone files that handle the recent changes to Daylight Saving Time. The included files are current as of January 8, 2007.

Java Printing

Radar #4729927

Print service lookup returns null results

Description:

When contact with a printer could not be established, PrintServiceLookup.lookupPrintServices may have returned an array of PrintServices objects that contained null entries.

Resolution:

Printers that cannot be contacted are no longer added to the available printers list. Also, the array returned by PrintServiceLookup.lookupPrintServices only contains valid PrintService objects.

Radar #4733025

Printer changes ignored

Description:

Changing the printer in a javax.print print dialog was sometimes ignored, causing print jobs to route to the default printer.

Resolution:

All print jobs go to the printer specified using the javax.print print dialog.

Java SWT Support

Radar #4548747

SWT embedding

Description:

Support for embedding AWT frames into an SWT-based application required a separate download.

Resolution:

The SWT embedding patches are included with Java for Mac OS X v.10.4 Release 5. The patches require Eclipse 3.2RC3 and later. See the Package org.eclipse.swt.awt documentation for more information on SWT AWT embedding support.

Radar #4558197

AWT frames embedded in SWT composites

Description:

AWT embedded frames would not appear when you created a Composite, set its size, and then added the embedded AWT frame.

Resolution:

Embedded frames always appear, regardless of the size of the parent Composite at creation time.

Radar #4698426

Crashes when embedding AWT Frames in SWT Shells

Description:

Embedding an AWT Frame in an SWT Shell caused crashes shortly after the shell appeared.

Resolution:

Embedding an AWT Frame within an SWT Shell no longer causes crashes. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=171105 for more information.

Radar #4880638

Crashes when embedding AWT Frames in SWT Shells after using SWT Browsers

Description:

An SWT-based application crashed if the application used an SWT Browser before embedding an AWT Frame in an SWT Shell.

Resolution:

Embedding an AWT Frame after using an SWT Browser no longer causes crashes. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=163629 for more information.

Radar #4916044

Crashes when closing embedded AWT Frames

Description:

SWT-based applications crashed after disposing of an embedded AWT Frame and then continuing to work with the window.

Resolution:

Closing an embedded AWT Frame and then working with its window no longer causes crashes. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=162687 for more information.

Java Virtual Machine

Radar #4843607

Concurrent Mark Sweep Garbage Collection Issues

Description:

Applications that use the +UseConcMarkSweepGC flag (Concurrent Mark Sweep Garbage Collection algorithm) were often unstable.

Resolution:

Applications that use the +UseConcMarkSweepGC algorithm execute properly.

Radar #4848029

Crashes when using the -server option

Description:

In some situations, running applications using the C2 compiler (-server) on Intel-based Macs crashed during Just-in-time compilation.

Resolution:

The C2 compiler on Intel-based Macs is considerably more reliable in this release.

Java Web Start

Radar #4791213

Java Cache Viewer crash

Description:

Java Cache Viewer crashed if the icon element’s name attribute in a JNLP file did not have a file extension.

Resolution:

Java Cache Viewer accepts any file name for icon elements.

Radar #4821360

JNLP applications use incorrect version of Java Web Start

Description:

JNLP-based applications that use Java 1.4.2 or 1.3.1 were started with a different version of Java Web Start than J2SE 5.0 JNLP-based applications. This caused caching issues and other behavioral issues between versions.

Resolution:

All JNLP applications are launched using the Java Web Start version installed by J2SE 5.0 using the Java Virtual Machine requested by the JNLP file.

Other Resolved Issues

Table 1-1 lists numerous issues present in previous versions of Java for Mac OS X that are resolved in Java for Mac OS X v10.4 Release 5.
