Java Applets

Radar #3819521

Java should have a way to run applets as their own process.

Description:

Java applets should be able to be run as their own processes, independent of the browser.

Resolution:

Java for OS X v10.5 Update 4 contains a prototype of the NPAPI-based Java Plugin2, which runs separately from the hosting browser process. It is present in /System/Library/Frameworks/JavaVM.framework/Resources/JavaPlugin2.plugin, and is a developer-only feature at this time.

Radar #6391767

JavaScript onload handler deadlocks with Java Applet security dialog.

Description:

On web pages containing a Java applet with signed content, any onload JavaScript handler that touched the Java LiveConnect support would logically deadlock with the modal security dialog.

Resolution:

LiveConnect calls sent to the applet while the security UI is present are dropped. A null instance of the applet is returned, because the applet is not actually alive yet.

Radar #6434637

Firefox does not use J2SE 1.4 when it is selected in Java Preferences.

Description:

The Firefox JavaEmbeddingPlugin read an internal property to determine which Java plug-in to load, and the property was removed.

Resolution:

This property has been replaced for older versions of the JEP, but will be removed in the future. Future versions of the JEP use the /usr/libexec/java_home command to determine which plug-in to load.

Java Application Support

Radar #5622562

Double-clickable Java applications have no way to express architecture requirements.

Description:

Java applications have no way to express to the JavaApplicationLauncher.framework their architecture requirements or preferred architecture. Checking the "Run in 32-bit mode" checkbox in the application's Finder Get Info window does nothing.

Resolution:

The JavaApplicationLauncher.framework no longer changes the architecture of a double-clickable application based on the JVM order in Java Preferences. Now, the architectures present in the JavaApplicationStub determine the architectures application can launch in. The order of the architectures in the LSArchitecturePriority key in the application's Info.plist now determine the preferred architecture to launch the application in. Additionally, the "Run in 32-bit mode" checkbox in the Finder Get Info window now functions as expected for Java applications. The JavaApplicationLauncher.framework now selects the first compatible JVM that can run in the architecture that application was launched in by Launch Services.

Radar #6474860

No way to choose JVM version from command line, no way to determine $JAVA_HOME.

Description:

OS X has no way to provide a valid $JAVA_HOME path that respects the order of JVMs in Java Preferences and handles version/architecture constraints.

Resolution:

/usr/libexec/java_home now prints a valid $JAVA_HOME path and takes several arguments to constrain its selection. See the java_home man page for more information.

Radar #6633526

JavaNativeFoundation's JNFObtainEnv() fails to set up a context classloader.

Description:

When JNFObtainEnv() attaches a thread to the JVM, it does not set up a context classloader for that thread.

Resolution:

This issue has been resolved.

Radar #6512564

Command-clicking on JLists and JTables resets selection.

Description:

Command-clicking on JLists and JTables would reset the selection instead of extending it when any slight motion occurred during the click.

Resolution:

This issue has been resolved.

Radar #6585910

Resolution:

Pasting and dragging image data into Java applications now works correctly.

Radar #6276671

Toolkit.getScreenResolution() reports unexpected values, causes unusual scaling.

Description:

Toolkit.getScreenResolution() began reporting the physical screen resolution, which caused unusual scaling in some apps. Toolkit.getScreenResolution() now reports 72 dpi, or a multiplied value if the User Interface Scaling setting in Quartz Debug specifies a higher UI scale factor. The resolution of physical displays can still be obtained by obtaining the GraphicsConfiguration of the screen and evaluating the transform returned from GraphicsConfiguration.getNormalizingTransform().

Resolution:

This issue has been resolved.

Radar #6434346

Starting the AWT from native launchers fails to properly register application.

Description:

Instantiating the AWT from some Java native launchers (like some based off of the simpleJavaLauncher ADC example) which don't create a Cocoa or Carbon event loop failed after installing Java for OS X v10.5 Update 2. This would cause windows to show up, but never become foreground.

Resolution:

The AWT now recognizes when it is instantiated by a custom launcher and performs the proper application registration.

Radar #6472766

Menus using brackets as shortcuts show as curly braces.

Description:

Menu items using brackets as menu shortcuts would show as curly braces instead.

Resolution:

This issue has been resolved.

Java Deploy

Radar #6681082

Java signed content dialog asks users to trust certificates.

Description:

Java Graphics

Radar #5607632

Sun2D Image scaling is extremely slow with images obtained from ImageIO.

Description:

The native image type returned from ImageIO was not a type optimized for use by the Sun 2D renderer, and could result in extremely long pause times when using BILINEAR or BICUBIC scaling. Java SE 6 is not affected.

Resolution:

This issue is addressed in J2SE 5.0 by pre-converting the native image type returned from ImageIO when using the Sun2D renderer.

Radar #5719903

Poor graphics fidelity, performance in J2SE 5.0.

Description:

The Sun2D renderer in J2SE 5.0 has many unaddressable performance and fidelity issues, including poor aliased circle drawing, slow anti-aliased primitives, very slow image scaling, and occasional crashes.

Workaround:

The Sun2D software renderer is still available via -Dapple.awt.graphics.UseQuartz=false.

Resolution:

The default graphics renderer for J2SE 5.0 has been switched back to Quartz. In Java SE 6, the quality and the performance of the Sun2D renderer is significantly better, so the default renderer for Java SE 6 remains Sun2D.

Radar #6674516

This issue has been resolved.

Radar #6565385

Java SE 6 HotSpot function compiler threshold reduced from 10000 to 1500.

Description:

The HotSpot function compiler threshold for Java SE 6 has been reduced to offer faster startup time for graphical applications. The previous value of 10000 is appropriate for server applications, however performance for graphical apps was shown to be improved by simply lowering this threshold to the default client value of 1500.

Workaround:

Pass -server to launch using the previous value.

Java InputMethods

Radar #4657992

Java Input Method Hotkey has been merged into Java Preferences.
