-------------------------------------
Summary: Remove from all caches when Groovy script is removed from
Camel script cache
Key: CAMEL-10732
URL: https://issues.apache.org/jira/browse/CAMEL-10732
Project: Camel
Issue Type: Bug
Components: camel-groovy
Affects Versions: 2.18.1, 2.17.4, 2.16.6
Reporter: Zoran Regvart
Assignee: Zoran Regvart
Camel's GroovyLanguage maintains a cache of Groovy class scripts up to maximum
of 1000 entries. When the limit of 1000 entries is reached the LRU cache
removes the least used ones.
The LRU cache removes only the Script classes it does not remove all the
references that still remain to that class and this causes a memory leak.
The remaining references are in Groovy metaclass registry, Groovy ClassInfo
reflection support cache and Java Beans Introspector cache.
All of these can be easily removed on removal from the Camel LRU script cache
by invoking {{org.codehaus.groovy.runtime.InvokerHelper.removeClass}}.
