I appreciate changes that make it easier to monitor and debug applications. Looking forward to some small goodies that I haven't heard much about before:

http://openjdk.java.net/jeps/228 - Add More Diagnostic Commands. For example more insight into JIT:ed methods and the code cache.

http://openjdk.java.net/jeps/158 - Unified JVM Logging. Logging from the JVM, e.g. GC logging and classloader logging, are configured and printed uniformly.

http://openjdk.java.net/jeps/259 - Stack-Walking API. Efficient API for walking the current call stack.

Oh, nice! At any given moment in time, how many server CPUs are burning cycles to create a full StackTraceElement array, just because the logger is set up to provide the convenience of call site information with every write?
