I am running the tests quite frequently and haven't encountered this one
yet. What operating system, java version, maven version are you using?

Looks like a line-ending issue.
I'm on OSX, when comparing
src/test/resources/openjdk/SampleSun1_6_0PrintHeapAtGC.txt
and the contents of
src/test/resources/openjdk/SampleSun1_6_0PrintHeapAtGC.txt.gz

the text in the gz has line endings of 0D 0A while SampleSun1_6_0PrintHeapAtGC.txt has just 0A

The size of SampleSun1_6_0PrintHeapAtGC.txt is 2944 bytes, while the size of the same file in the gz is 2976 bytes.

[kminooie]

Yup, I removed the SampleSun1_6_0PrintHeapAtGC.txt.gz, and gziped the SampleSun1_6_0PrintHeapAtGC.txt and it worked. thanks

[chewiebug]

Hmm, this seems to be quite tricky. In #120 someone has the same failure on a windows platform. Maybe, I'll have to rewrite this test to make it run on all platforms.

[chewiebug]

I have pushed a fix to the repository. Does the test failure now dissapear?

[cgrinds]

Yes, with your latest fix TestHttpUrlConnectionHelper passes.

[chewiebug]

Thanks a lot for checking!
