Explore the evolution of Garbage Collection in Java from JDK 8 to JDK 18 in this 25-minute conference talk presented by Thomas Schatzl, an OpenJDK Garbage Collection Engineer at Oracle. Dive into the performance improvements and key enhancements of the G1 garbage collector across 10 releases and over 2000 improvements. Learn about the design principles, throughput improvements in Parallel GC, latency enhancements, and footprint optimization techniques. Gain insights into the current garbage collectors, focus areas, and tradeoff dimensions. Discover what's in the pipeline for G1 and walk away with key takeaways to optimize your Java applications' garbage collection performance.
