---------------------------------
Summary: Leak in ReflectionUtils annotation cache. Value should
use WeakReference
Key: NIFI-15388
URL: https://issues.apache.org/jira/browse/NIFI-15388
Project: Apache NiFi
Issue Type: Bug
Reporter: Bob Paulin
When org.apache.nifi.util.ReflectionUtils invoke methods are called annotations
are cached in a WeakHashMap. While keys (Class) in the WeakHashMap are weak
references the values (Methods) are strong references. The classes can not
then be garbaged collected because the Methods have a reference to there class.
So the values that are added to the cache should also be wrapped in a
WeakReference. Then the classes can be garbage collected.
