Aha! I recall that, when I made a standalone test class, this call crashed the JVM. The unexpected outcome is that openjdk8 works fine even with LCMS 2.6; so perhaps JDK 8 changes the way it uses LCMS. > I've installed debug symbols and sources in my machine, the issue is > happening because we get a CMMException in this method: [...] > mdl.getTagData(profileID, tagSignature, tagData); [...] > which returns null, which in turn cases the NPE. > The CMMException exception states: > java.awt.color.CMMException: ICC Profile header not found > at sun.java2d.cmm.lcms.LCMS.getTagData(Native Method) [...] > As you can see we're failing indeed in a native method.

But does this mean YCbCr conversions using toCIEXYZ are broken on this platform since the JAI-EXT merge? Is this a significant regression? Should we recommend openjdk8 over openjdk7 for impacted users? > However, on Travis it builds fine, they claim to be running Ubuntu 12.04 > LTS (maybe the issue is new, affects only 14.04 series). Travis CI logs state they are running 12.04 LTS; according to Ubuntu, 12.04 LTS uses LCMS 2.2 which does not exhibit the bug. I have not tested 14.04 but 14.10 and later have the library that should fail (I confirmed the failure with the Ubuntu 14.10 library under Debian).
