Hi,
under OpenJDK7 I'm seeing this build failure:
-------------------------------------------------------------------------------
Test set: org.geotools.image.ImageWorkerTest

Tests run: 22, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 2.276 sec

Now... it seems to be a write related failure, if I put a breakpoint right
after
worker.writeJPEG(outFile, "JPEG-LS", 0.75f, true);
and look for outFile, indeed nothing seems to be able to open it (file
output.jpeg, attached)
Now... the issue seems to be related to the OpenJDK 7 + JAI native libs
installed togheter.
If I run JDK 6 + native JAI the test passes, but the test file cannot,
again, be opened by
anything (besides the JDK itself, that is). Sample attached,
output-jdk6.jpeg (hint,
the output.jpeg and output-jdk6.jpeg files are identical, it just seems
that JDK 7
is not able to read back the crap it's writing out).
When native JAI is not available the test passes but... it's writing out
the same unreadable
file, but the test passes because the code is no trying to read it back! :-p
Long story short, it seems calling:
worker.writeJPEG(outFile, "JPEG-LS", 0.75f, true);
never actually generates a valid JPEG file?
Cheers
Andrea
