// Note: When trying to provoke a metaspace OOM we may generate a lot of classes. In debug VMs this
// can cause considerable wait times since:
// - Compiler Dependencies verification iterates the class tree
// - Before exit, the CLDG is checked.
// Both verifications show quadratic time or worse wrt to number of loaded classes. Therefore it
// makes sense to switch one or both off and limit the metaspace size to something sensible.
// Example numbers on a slow ppc64 machine:
// MaxMetaspaceSize=64M - ~60-70K classes - ~20min runtime with all verifications
// MaxMetaspaceSize=16M - ~12-15K classes - ~12sec runtime with all verifications
// MaxMetaspaceSize=16M - ~12-15K classes - VerifyDependencies off - ~3seconds on ppc
