John Wagenleitner resolved GROOVY-7733. --------------------------------------- Resolution: Duplicate > Can't unloaded Groovy classes - PermGen Erros > --------------------------------------------- > > Key: GROOVY-7733 > URL: https://issues.apache.org/jira/browse/GROOVY-7733 > Project: Groovy > Issue Type: Bug > Components: groovy-jdk > Affects Versions: 1.0 > Environment: linux,windows > Reporter: Itay Hudedi > Priority: Critical > > I have a legacy system that is extensively using Groovy version 1.0 and > currently I can not update Groovy to an updated version. From time to time > I'm getting a PermGen error due to the fact that all the Groovy > classes/scripts are kept in memory even if no one is using them any more. > I'm trying to figure out what is the correct way to unload those classes > after I've finished using them. > I'm using the following code to create the Script object: > GroovyShell shell=new GroovyShell(); > Script script = shell.parse("ANY_TEXT"); > ..... > And I'm trying the following code to unload the generated class: > MetaClassRegistry metaClassRegistry = MetaClassRegistry.getIntance(0); > metaClassRegistry.removeMetaClass(script.getMetaClass().getClass()); > metaClassRegistry.removeMetaClass(script.getClass()); > metaClassRegistry.removeMetaClass(script.getBinding().getClass()); > script.setBinding(null); > script.setMetaClass(null); > script = null; > Unfortunately, this doesn't seems to work because I keep on getting a PermGen > error. How can I unloaded groovy classes and keep the PermGen size reasonable? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
