Enhancements in Java 2 Standard Edition for Solaris v. 1.2.2_05a

The Java 2 Standard Edition v. 1.2.2_05a is the latest release of Java 2 platform for the Solaris operating environment. It is a bug-fix release of v. 1.2.2_05 (without the "a") of the same product and includes the following new features and enhancements.

Scalability improvements to over 20 CPUs

Improved handling of concurrency primitives and threads has increased the performance of multithreaded programs and significantly reduced garbage-collection pause times for programs that use many threads.

Improved JIT compiler optimizations

The JIT compiler performs the following new optimizations: inlining of virtual and non-virtual methods, CSE within extended basic blocks, loop analysis to eliminate array bounds checking, and fast type checks.

Text rendering performance improvements

Several graphics optimizations have significantly improved text rendering performance for Java 2 Standard Edition on Solaris software platforms without Direct Graphics Access (DGA) support. These platforms include Ultra 5; Ultra 10; the Solaris Operating Environment, Intel Platform Edition; and all remote display systems.
