We are planning to integrate "Event-Based JVM Tracing" into hotspot-rt next week. This is (more or less) a forward port of the implementation that already exists in jdk7u. The main difference compared to jdk7u is the adaptations made to support metaspace instead of permgen. The changes have been thoroughly tested internally, but given the size of the changes there is a large risk of unforeseen problems.
