5 ConcurrentModificationException in load test - ID: 2884515
Last Update: Comment added ( nobody )

I'm getting a ConcurrentModificationException for my load test when running
on Linux. On Windows I haven't seen this issue. Attached is log output.
It's been obfuscated a bit to hide corporate stuff.
Environment:
SUSE Linux 64-bit
JRE: IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Linux amd64-64
j9vmxa6423-20090707 (JIT enabled))
soapUI 3.0.1 nightly 20091022

Hmm, maybe a spoke too soon. It works much better with 3.0.1-20091027, but
i did managed to get a CME after several runs. This was with IBM JRE 1.5.0.
The stacktrace is like the attached for jdk1.6.:

Tested with IBM J9 JRE 1.5.0 and it works like a charm. Thanks!

Hi!

thanks for reporting.. the upcoming nightly build attempts to fix this on
jdk 1.6, can you give it a try and let us know?

regards!

It might be of interest to know that for the endpoint being used here, I
have property expansion in the URL. I also start loadtestrunner.sh defining
the -h switch.

Actually, when looking more closely, I see that the CME is thrown at a
different place when executing with JDK 1.6. See attached log.

Tested on the same server but with Sun JDK 1.6.0_13-b03. The issue still
exists.
