Potential native memory use in reflection delegating classloaders

Troubleshooting


Problem

A high number of classloaders of type sun/reflect/DelegatingClassLoader, which are used to load sun/reflect/GeneratedMethodAccessor classes, can indicate a potential large native memory footprint.

Symptom

The process size for the application server will grow quite large. You might also see OutOfMemoryError’s thrown.
