This release is based on the Azul Zing Build of OpenJDK (Zing) 26.02.100.0 and corresponds to the following OpenJDK versions:

Zing 26.02.101.0 includes the Metaspace MemoryPool MXBean, for OpenJDK compatibility. This MXBean initializes a memory manager and dummy memory pool. However, since Zing tracks metadata in the Java Heap, included in the existing Zing Heap MXBean, it always reports 0 usage. The Metaspace MemoryPool MXBean is disabled by default and can be enabled using the command line option -XX:+EnableMetaspacePoolMXBean.
