[jboss-jira] [JBoss JIRA] (JASSIST-148) StackOverflowError when using $sig and $class in call to static method

[Shigeru Chiba (JIRA)]

    [ https://issues.jboss.org/browse/JASSIST-148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12659410#comment-12659410 ] 

Shigeru Chiba commented on JASSIST-148:
---------------------------------------

Agent seems to try to transform javassist.* and cause an infinite regression.
Agent.transform() should not transform the bytecode if the class name is java.* or javassist.*.
