[jira] [Updated] (GROOVY-10819) Meta class registry corruption leading to stack overflow

["Eric Milles (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-10819?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles updated GROOVY-10819:
---------------------------------
    Description: 
Consider the following:
{code:groovy}
String.metaClass.methodName = {
  // ...
}
"foo".methodName()
{code}

After executing this, the {{ClassInfo}} registry contains an entry java.lang.String: \{theClass: java.lang.Class, ...\}.

As additional Groovy code is executed, {{PojoMetaClassSite}} entries can fail cache check and create a new {{CallSite}} and it too fails cache check and so on until stack overflow.
