These release notes describe its new features, platform requirements, installation, limitations, known problems and issues, and documentation for Oracle Java SE Embedded.

This document contains the following topics:

New and Changed Features

The following changes are included in Release 8 Update 33.

  • ARMv7 SF ABI binary is no longer provided. The ARMv7 SF ABI will still be supported through the ARMv5 SF ABI binary but there is no support for the server VM. This binary supports the client JIT compiler only.
  • ARMv5 headful binary and support is no longer provided.
  • The ARMv6 Embedded bundle now provides support for both ARMv6 and ARMv7 devices. The previous Java Embedded 8u6 release only provided support for ARMv6 devices in the JDK for ARM bundle.
  • Starting with 8u33 release, SE Embedded releases will no longer include PowerPC platforms. Both the 32-bit PPC platforms (e500v2 and e600) that were previously available, are no longer offered.
  • Starting with 8u33 release, SE Embedded releases will no longer include JavaFX.

2 Platforms and Requirements

See Oracle Java SE Embedded System Requirements.

3 Installing Oracle Java SE Embedded

Oracle Java SE Embedded 8 is a modular system that must be configured before launching by selecting components and creating a custom JRE to suit your device and applications, using the included jrecreate tool. See Oracle Java SE Developer's Guide.

The server JVM described in Oracle Java SE Embedded Developer's Guide is only available on the following targets:

  • ARM v7 hard float

  • i586

5.2 Native Memory Tracking Support is Limited on ARM Targets

For ARM devices, the -XX:NativeMemoryTracking=detail java command line option produces a warning and defaults the setting to summary.

6 Learning Resources

The Oracle Java SE Embedded page on Oracle Technology Network contains information such as links to documentation, system requirements and FAQs. See http://www.oracle.com/java/technologies/javase-embedded/javase-embedded.html
