Loading rulebase several times causes Metaspace OOM error
Issue
We deploy rule content using compiled executable model to tomcat container. The rule content can be hot deployed i.e, replaced by the new rule content while the service is running.
We are finding after several deployments the metaspace memory runs out due to classes never unloads:
| HeapSize | MetaspaceSize | MeataspaceOOM |
