Hi all,

could you please review this small fix for CTW tests? the tests fail if the line w/ last class id is mixed w/ another line in output. this happens b/c cerr of CTW process is redirected to cout, the fix redirects cerr into a separate file.

webrev:  http://cr.openjdk.java.net/~iignatyev//8191273/webrev.00
jbs: https://bugs.openjdk.java.net/browse/JDK-8191273
testing: applications/ctw/modules tests

Thanks,
-- Igor
