Grails 2.5.1 (with updated Groovy version)
Win 7
Java HotSpot 64 v1.8.0_66-b17
Description
I am seeing a memory leak in my Grails app, which uses a lot of expando metaclass properties.
From looking at the GC path, I believe this leak comes from the Groovy framework. I have attached a screenshot from jvisualvm which shows a path to the GC root. The path doesn't appear to contain any weak/soft reference types.
Please let me know if you think my analysis is mistaken. I don't have a strong understanding of Groovy framework internals.
GC via JMX does not remove these objects.
Updating my BuildConfig to use Groovy 2.4.9 (with forked compile) did not fix the issue.
(Note: Some of the dependencies in the attached BuildConfig are proprietary and not available from the grails plugin repo.)
