Class java/util/UUID could not be instrumented

[katheri...@gmail.com]

I am trying to run Jacoco for junit testing in Jenkins via ant task.

Referring to the online doc, I wrap my junit task in ant with jacoco.coverage.
When I run the junit task in linux command line, everything works fine. However, when I trigger the junit task from Jenkins, it throws the following exception:

[jacoco:coverage] Enhancing java with coverage

I also tried to run the example ant task shipped with the jacoco distribution and got the same result (works from command line, but exception from jenkins)

I suspect something in Jenkins or the tomcat server that hosts jenkins conflict with this java.util.UUID.

Has anyone encountered this before? Thank you so much for your help in advance :)

This happens with Java 8 (which not yet supported by JaCoCo).

What JRE version are you using?

[katrin]

Sorry I should have provided the versions:

JDK 1.6.0_17
Tomcat 6.0.35
Jacoco 0.6.2.2013020300002
Jenkins 1.513

[Marc Hoffmann]

This is strange. Are you sure this is the exact JVM which is also used
when running under Jenkins?

Can you configure your Jenkins Job to run the Ant script with the
"-debug" option. This should provide two infos in the log file:

1) The exact JDK Version
2) The command line used to execute your unit tests

Can you please doublecheck 1) and provide send 2)?

Thanks,
-marc

[katheri...@gmail.com]

This is SOOO strange - I can't understand at all:

First I tried to run the test task with -debug from Jenkins, and no errors anymore.
Then I tried to run the test task without -debug from Jenkins, still no error anymore.

FYR, below is some output from my ant task:

Do you use multiple Slaves in Jenkins? Maybe there are different JREs
on different nodes...

[katrin]

No, I didn't setup any slave in Jenkins, and I think my servers don't even have jdk 1.8 installed......

Anyway I am trying a full build on Jenkins now, will update you of my result ;-)

[katrin]

Unfortunately the issue persists again.....

What is the vendor of your JRE? Can you please execute

java -version

on your Jenkins node?

Thx,
-marc

[katrin]

[0]> java -version
java version "1.6.0_17"
OpenJDK Runtime Environment (IcedTea6 1.7.5) (rhel-1.16.b17.el5-i386)
OpenJDK Server VM (build 14.0-b16, mixed mode)

[Marc R. Hoffmann]

I've personally never tested OpenJDK 1.6, but so far no issue was
reported here. So I guess it is something specific to your setup. Maybe
you have a chance to figure out what the difference is between the
builds which work and the builds which fail?

-marc

[katrin]

I finally found out that the issue will happen whenever I run the build on Jenkins with coverity enabled. It doesn't matter if the junit test was run as a post-build task or even after coverity report generation.

[yoges...@gmail.com]

I am seeing same error and I am using Java8. On our new project, we are using Java 8 (and can not use Java 7).

Any ideal, when can we expect Java 8 supported??

[Marc R. Hoffmann]

Here you find a preview build which supports Java 8:
https://github.com/jacoco/jacoco/issues/74

A official release depends on the finalization of the Java 8 spec.

Hi,

we don't have any experience or tests with J9.

Hi, 

I have this issue with jdk1.8.0_45 and jacoco 0.7.5 and 0.7.6. If I understood well, this was solved from jacoco 0.7.0 (https://github.com/jacoco/jacoco/issues/74). 

The stack is the following:

FATAL ERROR in native method: processing of -javaagent failed

I'm configuring JAVA_OPTS in this way:

export JAVA_OPTS="-javaagent:/tmp/jacoco/lib/jacocoagent.jar=output=tcpserver,address=*,port=6300,includes=*"

Any idea to solve this?

Thanks!

[Evgeny Mandrikov]

Hi,

Could you please post output of "java -version" ? And describe a bit more application under measurement ?

[Luis Thur]

Hi Evgeny!
Yes, the output for java -version is:

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Thanks for your time.

[Diego Bosin]

Hi Evgeny,

In addition to what Luis said, the application is a rest API over grails 2.4.2, which use an oracle db. Do you need any other details?

Thanks!

Diego.

[Evgeny Mandrikov]

Ok, from here some thoughts: I've used for quite a while JaCoCo with JDK 8u45 on various projects without troubles. So don't think that problem relates to JDK and have feeling that it relates to application under test. According to your description won't be easy to quickly construct something similar as reproducer. Thus maybe you can provide such a reproducer? This will greatly speedup investigations. Also anyway I would suggest to try most recent JDK version just in case.
