I'm confused now. Why would we exclude 32-bit Windows? It is the only
platform where the original bug could be reproduced and where OOME or
NPE is thrown in the test. With 64-bit platforms, it's nearly
impossible to exhaust native memory to the state where OOME or NPE is
thrown. It's the reason why the unmodified test takes too long on
64-bit Windows.
I though the comment below was about the current bug:
In fact, I reproduced the bug only on Windows and only on 32 bit
If it is slow on win x64 only, then it really looks like a product bug.
It should not be much different from the lin/mac x64, 3-4 min vs 30-40
min...
I wasn't clear enough when referring to different bugs.
I have submitted
https://bugs.openjdk.java.net/browse/JDK-8233028
to investigate slow performance of ICMColorDataTest which could indicate
a product bug.
What about this patch?
By reducing the number of iterations, the time to complete the test on
64-bit Windows is decreased from about 30 minutes to about 5 minutes.
