How does it handle memory leak investigations?

It provides specific commands for generating heap dumps (jmap) and analyzing object retention patterns using industry-standard tools and methodologies.

Does this skill require specific Java versions?

While many commands work with older versions, it is optimized for modern JDKs (Java 11, 17, and 21+) to take advantage of features like ZGC and JFR.

Which Garbage Collectors does this skill support?

The skill supports a wide range of GCs including G1, ZGC (including Generational ZGC), Shenandoah, Parallel, and Serial GC, providing specific presets for each.

Can I use this skill to optimize Java applications in Docker?

Yes, it includes container-optimized presets such as MaxRAMPercentage and UseContainerSupport to ensure the JVM operates efficiently within cgroup limits.

Does it help with code-level performance testing?

Absolutely. It provides standardized templates for JMH (Java Microbenchmark Harness) to help you write scientifically accurate performance tests.
