High CPU in AbstractClassLoaderValue.computeIfAbsent calls

Issue

• Moving to java 11+, we are see that we can reach a state with excessively high CPU and heavy thread blocking in jdk.internal.loader.AbstractClassLoaderValue.computeIfAbsent calls like below. We have to restart the app to address it:
