64-Bit Browser Support for Java Plugin and Java Webstart
Note, if you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit JREs in order to have Java Plug-In for both browsers.
- Old Java plugin
- Java Kernel
- JQS
- DeployTK
- SSV
- Patch in Place
- Online installer
- Java auto download
- Java auto update
JavaFX
Improved application startup and runtime performance are provided.
AWT Support
- Limited mixing of heavyweight and lightweight components is supported. Limited mixing means that some components may not be handled perfectly. This includes, but is not limited to, support for non-opaque lightweight components.
- Translucent windows may not work correctly on some X11 systems. This problem is described in 6762511.
- The Security Warning used with the toplevel windows of an untrusted application has been improved to make it less intrusive and more subtle.
Windows Server 2008 Support
Supported ConfigurationsPerformance Improvements
Performance improvements have been made in the following areas.
- Graphics performance improvements for:
- Anti-aliasing drawing and filing
- Non-anti-aliasing transformed rectangles and single wide lines
- Java Webstart startup time
