Hi all, JVMTI is a great step forward to supporting extensible profiling and debug tools. I believe that we should work to ensure that Apache Harmony implements all JVMTI functionality including optional functionality in the JVMTI specification. This will ensure that all tools implemented to the JVMTI standard will work seamlessly on Apache Harmony and will help make Harmony a vehicle for developing new JVMTI based tools.
It is important to note that the JVMTI interface standard is inherently extensible. This extensibility interface allows a VM implementation to expose additional, valuable, profiling interfaces that go beyond what the JVMTI standard provides. Apache Harmony should be designed such that JVMTI support is extensible. We can then consider suggesting some of the best of "today's" JVMTI extensions to the JCP to become part of the followon to JSR 163 for the next generation of JVMTI. I suggest the following requirements for Apache Harmony: All well formed JVMTI agents should function on Apache Harmony. Harmony should design its support of the JVMTI interface in an extensible manner to facilitate experimentation with JVMTI extensions. Regards, Chris Elford Intel Managed Runtime Division
