Issue

• Using image openjdk18-openshift:1.2-7, trying to override JVM options for -XX:MaxMetaspaceSize=<size>m. When setting this parameter in JAVA_OPTS using -XX:MaxMetaspaceSize=300m, Openshift overrides this value with -XX:MaxMetaspaceSize=100m.
  JVM startup log with final flags for metaspace below...
