IllegalClassFormatException

[heiko.r...@googlemail.com]

I am trying to use Jacoco with an app running on top of JBossAS7.1

I the server log I see this for some classes:

Any idea what I may be doing wrong?

Hi,

can you please provide some more lines after the "Caused by:
java.lang.ArrayIndexOutOfBoundsException"? This is where it gets
interesting.

What Version of JaCoCo are you using?

Thanks,

Hi,

thanks! It looks like ASM has a problem with the following class file:

org/rhq/enterprise/server/rest/ReportsHandlerBean$$$view26.class

Can you please provide this class file? If you can't locate it or the
file is dynamically created you might specify the classdumpdir option of
the JaCoCo agent, see manual:
http://www.eclemma.org/jacoco/trunk/doc/agent.html

Cheers,
-marc

Looks like dynamically created -- probably the "local interface" of an EJB, as the
source class uses only @Stateless and thus making this a no-interface EJB.

> file is dynamically created you might specify the classdumpdir option of

As I don't know if it is possible to attach files here, I've zipped up the relevant package
and put into dropbox at https://dl.dropbox.com/u/21627069/rest.zip

Thanks
Heiko

[Marc R. Hoffmann]

Thx! I can reproduce the problem. Might be an ASM issue as the class can
be disassembled with javap without any problems.

-marc

[Marc R. Hoffmann]

The problem seems to be ASM related, I opened a bug against ASM:

Thanks

Do you have an idea on how long ASM usually takes to fix those issues and release a newer version?

Heiko

[Marc Hoffmann]

I have no idea about their plans, but they're are already working on
ASM 5. So once they released ASM 5 we first need to migrate JaCoCo. So I
wouldn't expect a solution soon.

As the classes are generated at runtime anyways, why not simply exclude
the "$$$" classes from analysis? EclEmma has a preference settings for
this, the same applies for all other JaCoCo integrations.

Good idea.
Do those need "escapes" or such?

I have includes=org.rhq.server.rest.*,excludes=*.$$$* as arguments to the agent, but that seems to produce no output at all

Thanks
Heiko

[Marc Hoffmann]

How do you use JaCoCo? EclEmma, Ant, Maven?

As java agent directly on the running server like this:

RHQ_SERVER_ADDITIONAL_JAVA_OPTS="$RHQ_SERVER_ADDITIONAL_JAVA_OPTS -XX:-UseSplitVerifier -javaagent:/Users/hrupp/downloads/jacoco/lib/jacocoagent.jar=dumponexit=true,output=file,destfile=/im/rhq/rest-api-jacoco.exec,includes=org.rhq.server.rest.*,excludes=*.$$$*"

With all the testing / trying / fiddling I finally selected the wrong package name for inclusion, which explains the empty output.

Time for weekend :)

[Marc Hoffmann]

Can you please try just the following exclude parameter:

excludes=*$$$*

There is no dot in ReportsHandlerBean$$$view26

[Marc R. Hoffmann]

Hi,

ASM found out that the class file actually is invalid:

http://forge.ow2.org/tracker/?func=detail&atid=100023&aid=316418&group_id=23

Please report this issue to the tool generating the class files.

Thx,
-marc

Hi I got the following error. That was due to some auto generated class located in com/aepona/tws/aoc/AdditionalInfo floder. That was corrected by excluding those auto generated calasses by setting the property "excludes".

<jacoco:agent property="agentvmparam" destfile="target/jacoco.exec" excludes="com/aepona/tws/aoc/*"

Hi,

there is nothing we can do about this from JaCoCo side. Please report
the problem to the manufacturer of the tool which creates invalid
classes. JaCoCo expects input classes to be valid including correct
stack map frame information for classes >= Java 1.6.

Best regards,
-marc

Hi Heiko,

did you report a bug to JBoss for this? I have the same problem here...
