Metaspace OOME happens by creating KieContainer, executing rules, disposing KieContainer repeatedly.

Solution Unverified - Updated -

Issue

When I create a KieContainer, send requests to the KieContainer and dispose the KieContainer repeatedly, OutOfMemoryError: Metaspace occurs (in the case MaxMetaspaceSize JVM Option is given to the KIE Server). Also, this issue occurs only when request data to the KieContainer is of JSON format.
