Summary: Tweak cleanup DFA cache of parser
Key: GROOVY-11240
URL: https://issues.apache.org/jira/browse/GROOVY-11240
Project: Groovy
Issue Type: Improvement
Reporter: Daniel Sun
Assignee: Daniel Sun
Fix For: 5.0.0-alpha-4
We should keep the DFA cache as possible as we could, but the DFA cache is very
huge and results in OOM.
Our current solution is to set a threshold to cleanup DFA cache, but the
threshold is hard for users to evaluate reasonable value.
The new solution relies on GC, if the object referenced by soft reference is
collected by GC, we trigger the cleanup of DFA cache. We just need set the
threshold to {{0}} to enable the smart cleanup.
For better compatibility, we keep the existing cleanup as it is.
