I am posting this because I was not able to find anything on Net. Even I consider it now to belong into category obvious.

I am working on obfuscation of our project and was bitten by following exception when trying to use the obfuscated JAR:

java.lang.ClassFormatError: StackMapTable format error: bad class index

StackMapTable is feature of Java to provide faster class verification and you cannot configure Klassmaster what to do about it as you can with any proper class.

Eventually I found it works when built locally, but fails with version built by a build server. That helped me to find the culprit.

Solution

We were using old version of Zelix Klassmaster on server due to incorrect default home directory of Klassmaster. After changing path to use version 5.3 it works. It works also with 5.2.4b.
