Analyzer java-thread-state

# Name

java-thread-state - Java Thread States and Waits

This analyzer gives a compact view of Java thread creation, lifetime, and waiting. The bar chart compares thread start requests, run entries, exits, still-running threads, and recorded blocked/park waits. It also produces a lifetime histogram for threads that enter JavaThread::run during the trace and a wait histogram from futex waits made by all observed Java threads, including threads that already existed when tracing started.
