The OpenJDK Quality Group is promoting testing of FOSS projects with OpenJDK builds to enhance release quality.Starting with JDK 25, Metaspace and GC logs in HotSpot JVM will be separately tagged to avoid confusion.Metaspace-related log messages will now use the existing metaspace tag, distinct from GC logs.User-facing changes in jcmd are also made to reflect that Metaspace is not part of the GC Heap.
