[jboss-jira] [JBoss JIRA] (JASSIST-177) javassist.bytecode.BadBytecode on weblogic.jdbc.jts.Driver:
[

]
Shigeru Chiba resolved JASSIST-177.
-----------------------------------
Fix Version/s: 3.17.1-GA
Resolution: Done
This bug is because weblogic.jar has been compiled by Java 6 but contains JSR
instructions, which Oracle/Open JDKs do not use. It works on Java 6 but not Java 7, which
does not allow JSR.
I've modified Javassist so that it will not generate StackMapTables when it finds
JSR.
