Package: openjdk-6-jre
Version: 6b17~pre3-1
Severity: important
Hello,
while debugging why my JOSM didn't work anymore, I found this bug in OpenJDK:
$ update-alternatives --list java
/usr/bin/gij-4.3
/usr/bin/gij-4.4
/usr/lib/jvm/java-6-openjdk/jre/bin/java
/usr/lib/jvm/java-6-sun/jre/bin/java
$
$ /usr/lib/jvm/java-6-sun/jre/bin/java openjdkbug/Main
$
$ /usr/lib/jvm/java-6-openjdk/jre/bin/java openjdkbug/Main
Exception in thread "main" java.lang.NullPointerException
at javax.imageio.ImageIO.read(ImageIO.java:1434)
at javax.imageio.ImageIO.read(ImageIO.java:1390)
at openjdkbug.Main.main(Main.java:12)
$
As you can see, the same code throws a NPE with OpenJDK, while it runs fine
with Sun's JRE (in fact, using Sun's one, JOSM went fine too).
I'm attaching a minimal testcase, i.e. the code of the above Main.class.
I can say it worked before, but I can't define when this "before" exactly is.
It's after Dec, 19 for sure, since that's my last OSM edit (that is, I used
JOSM and it didn't miserably fail) before I used a fallback editor.
Since 6b17~pre3-1 has been uploaded just the day before (Dec, 18), I don't
exclude I didn't upgrade my system on that day, and I was still using
6b17~pre2-1.
Thanks,
David
