[jboss-jira] [JBoss JIRA] (JASSIST-160) Java.lang.VerifyErrors occur in specific cases when using javaassist with Java 1.7

From the PowerMock issue thread. Anyone trying to temporarily workaround this issue, adding the following argument -XX:-UseSplitVerifier does prevent this from occurring.

Java.lang.VerifyErrors occur in specific cases when using javaassist with Java 1.7 ---------------------------------------------------------------------------------- Key: JASSIST-160 URL: https://issues.jboss.org/browse/JASSIST-160 Project: Javassist Issue Type: Bug Affects Versions: 3.16.1-GA Environment: jdk1.7.0_03 on Windows XP SP 3 Reporter: Avner Singerman Assignee: Shigeru Chiba Attachments: jatest.zip We found at least two different cases where inserting bytecode using javaassist results in a class that cannot be loaded with Java 1.7. java.lang.VerifyError: Inconsistent stackmap frames at branch target java.lang.VerifyError: Bad return type in method The exact same code injection on the exact same classes works fine with Java 1.6. We upgraded to the latest version of javaassist - 3.16.1.GA, but it didn't solve the problem. I'm attaching to this bug a self contained example where you can see both type of errors.
