Analyzer java-jit-compile

# Name

java-jit-compile - Java JIT Compilation

This analyzer watches HotSpot compiler tasks as they enter the JIT compilation queue and as compiler threads start and finish them. It always reports queued and started task counts; when matching JVM debug information exposes the corresponding private fields, it also reports successful, failed, C1, C2, OSR, and regular compilation counts. A bar chart lists frequently compiled methods, while separate histograms show time waiting in the compiler queue and time spent compiling. In simple terms, it shows how the JVM turns frequently used bytecode into optimized machine code during startup and warmup.
