1.2 Hardware Must Support Streaming SIMD Extensions (SSE) 2

Oracle JRockit JDK R28.x does not support x87, the floating point extension to the x86 platform.

Hardware on which you intend to run the Oracle JRockit JVM must support SSE2 (Streaming SIMD Extensions): that is, Intel Pentium 4 or Pentium M; AMD Opteron or Athlon 64; or newer hardware.

1.3 J2SE 1.4.2 and JVMPI Not Supported

Oracle JRockit JDK R28.x does not support J2SE 1.4.2.

As a consequence of this change, JRockit JDK R28.x does not support JVMPI. Most tools partners use JVMTI, which continues to be supported.

1.4 Itanium Platforms Not Supported

Oracle JRockit JDK R28.x does not support the Itanium architecture.

Previous JRockit JDK releases are available and supported for Itanium platforms until all the dependent Oracle products reach end-of-life (EOL).
