OpenJDK Serviceability Development

This forum is an archive for the mailing list serviceability-dev@openjdk.java.net (more options) Messages posted here will be sent to this mailing list.
Java SE contains several technologies that allow Java programs to be debugged, profiled, monitored and managed. These technologies allow a tool written in the Java programming language to obtain information from the Java Virtual Machine(JVM) in a different process. These technologies typically:

    * Contain Java code in the J2SE repository
    * Contain native code in the J2SE repository
    * Contain native code in the HotSpot repository. This code implements interfaces that are used by the code in the J2SE repository. This typically involves some form of inter-process communication.
