The VM Options Explorer provides a comprehensive reference for OpenJDK 11 HotSpot virtual machine configuration flags. This tool catalogs thousands of runtime parameters that control garbage collection, compilation, memory management, and performance optimizations. Developers can browse options by category, JDK version, and experimental status.

Key diagnostic flags include AbortVMOnCompilationFailure and AbortVMOnException, which help developers catch critical runtime errors early. Performance tuning parameters like AdaptiveSizePolicyWeight and AggressiveOpts allow fine-grained control over JVM behavior. The explorer also documents deprecated options being phased out in newer JDK versions, helping teams plan migration strategies.

This reference serves as an essential resource for Java performance engineers and system administrators. By providing detailed descriptions, valid value ranges, and deprecation status for each flag, the explorer helps teams optimize their JVM configurations without trial-and-error experimentation. The tool supports multiple JDK versions, making it valuable for organizations maintaining heterogeneous Java environments.
