I have pointed out some changes below, but there is a serious problem. You are checking for the system arch using uname but the java architecture may not be the same.

For example we run 32-bit jdk on a 64bit system, this will cause test failures since we will be using the wrong path names. You can use the following to determine the java arch. % java -XshowSettings:props -version 2>&1 | grep os.arch This doesn't work (at least for me) unless the '-version' is removed. There was a bug which was fixed in 7u4/u6.

I also note that this seems to only be present in 7 and later (i.e. not 6), not that this will matter in this case. Correct, 7 and above.

Thanks Kumar On 08/13/2012 10:39 AM, Anthony Petrov wrote: The test looks great, and I like that it doesn't depend on the JAWT machinery, but tests the actual problematic RPATH entry only. I generally go for tests that verify behaviour (that jawt-linked programs are working) rather than implementation details (which changed, for example, when we switched from LDLIBRARYPATH to RPATHS).

+1 from me. Yes, good to have something that guards us from changing something unintentionally. Looks fine to me too. Cheers, Omair
