Hi,

Trying to instrument using command "mvn org.jacoco:jacoco-maven-plugin:instrument" & here is the exception thrown.

The same is working fine for other maven projects. It is failing only in this case. Also, it looks stack trace is pointing to " org.jacoco.core.instr.Instrumenter.instrument(Instrumenter.java:108)" . What may be the root cause of this ??

-Thanks,

Kesav.

Hi,

this is a known issue that can happen for very large methods: https://github.com/jacoco/jacoco/pull/177

The only work around for now is to exclude the problematic class ("ConfigDAO").

Regards,
-marc

It looks I can NOT list set of classes to be ignored in command line. correct ? It looks there is no User Property defined for excludes/includes similar to skip (jacoco.skip). Believe need to change pom.xml to define classes to be ignored. rt?

-Best Regards,

Kesav.

That's correct as per documentation http://www.eclemma.org/jacoco/trunk/doc/prepare-agent-mojo.html#excludes

Also, it looks this issue (https://github.com/jacoco/jacoco/pull/177) is going to be fixed in 0.7.8. correct ? When is 0.7.8 jacoco going to be released ?? Also, can you point me to documentation for applying this fix as patch to 0.7.7 jacoco???

No, this issue is NOT going to be fixed in 0.7.8. Read the comments on this issue carefully : it depends on fix in ASM library and we have no idea when ASM will be released.

Also, can you point me to documentation for applying this fix as patch to 0.7.7 jacoco???

You need to build ASM from their SVN trunk and update JaCoCo to use your build of ASM.

I wouldn't recommend to do this, because custom build - is a custom build, you'll be on your own in terms of support in case of troubles.

Instead - use official JaCoCo release to be safe and simply exclude problematic class as Marc said.

P.S. number of question marks doesn't increase importance/priority of your email over others in queues of participants of this mailing list ;)
