JSR-255, the Java specification for a successor to the Java Management Extensions (JMX), is not being incorporated in Java 7. JSR255 is aimed at updating the JMX API to make use of Java's generics and annotations support. The previous version of JMX was incorporated in Java 5, and allowed developers to create MBeans which could be used to monitor and manage everything from the Java runtime system to application frameworks.

The announcement came from the project lead, Eamonn McManus, in a blog posting, where he explained that the JSR had been pushed out of the JDK 7 feature list because of resource constraints.

McManus said that the plan now was to target JDK 8, and that over the next months, he will be creating a new OpenJDK project, "JMX2" where the development reference implementation of JSR255 will continue. The JDK 8 planning begins at the end of the JDK 7 development cycle and is expected at the beginning of next year.
