Understanding HotSpot JVM Performance with JITWatch

Learn about the Just In Time (JIT) optimisations made by the HotSpot JVM to dynamically optimise the performance of your code at runtime. Learn about using the free and open-source JITWatch tool to analyse the JIT compiler decisions made by the JVM during the execution of your program. Discover which of your methods were inlined, which allocations were eliminate through escape analysis, and identify safepoint poll points in your code.
