Metaspace consumption

Each deploy of KJar consumes additional Metapaspace memory, undeploy doesn't free allocated memory. Our solution uses a lot of custom work items and other classes implementing business logic. Each deploy of KJar causes loading a copy of all the classes. In our case approximately 20MB. Having several deployed KJars occasionally updated we faced out of memory error with XX:MaxMetaspaceSize=512m. Finally, we are planning to have more than 30 KJars deployed on a production environment. Increasing MaxMetaspaceSize doesn't solve the problem.
