> Can't we just use a SoftReferenceMap or something ? is the leak just holding onto entries in that Map? In fact, the leak map([pmCache](https://github.com/datanucleus/datanucleus-api-jdo/blob/master/src/main/java/org/datanucleus/api/jdo/JDOPersistenceManagerFactory.java#L128)) caused by this problem belongs to [datanucleus-api-jdo](https://github.com/datanucleus/datanucleus-api-jdo), which is only a library that Spark depends on, and we should not modify its code because the problem is caused by the `IsolatedClassLoader` in Spark. The leak caused the memory to grow slowly and finally the STS SQL execution was very slow (continuous GC). -- This is an automated message from the Apache Git Service.
