Oracle JRockit (formerly BEA JRockit) is a well recognized JVM which has many advantages over Sun JVM. For example it overcomes the usual difficulties with PermGen space limitations of the Sun JVM, just to name one. In benchmarks in a real complex SOA project we have experienced performance advantages of JRockit over Sun on Linux of more than 50%!
Since today, JRockit 1.6 (R27.6.3) is now certified for SOA Suite 10.1.3.4 on Linux and Windows!
Please see the updated Oracle Fusion Middleware 10gR3 Certification Matrix.
