Hi Jayan,
thanks for reporting this! After some analysis it looks like you
encountered a special case we haven't considered before. Please see
technical details in the bug I just opened for this:
https://github.com/jacoco/jacoco/issues/177
The only work around I see for you is to exclude the JAR or class from
instrumentation.
Cheers,
-marc

This is strange, JaCoCo should never call
ClassWriter.getCommonSuperClass(). Can you please provide the
fully qualified version of the JaCoCo copy you're using?

I am using offline instrumentation feature of jacoco[Some of
the tests involve jmockit, I could not make the
on-the-fly-instrumentation work]. I am using latest jacoco to
instrument a war. This gets ClassNotFoundException from some
class (pre-compiled from jsp)
<jacoco:instrument destdir="instrumentedwar">
<fileset dir="wartemp" includes="**/*.war" />
</jacoco:instrument>
Exception:

The missing class is exist in
javax.servlet.jsp-2.2.0.v201112011158.jar (jetty8). It looks
like instrumentation looks for parent class;how do I pass it
to jacoco:instrument?
(Jacoco Version 0.6.3)
Thanks,
Jayan
