[Debian-med-packaging] Bug#558222: Imagej crashes with NullPointerException only java-gcj-compat is installed

[Manny Vindiola]

Hi,

I was worried that this might be a bug that only affected ubuntu so I
checked if it would run in a squeeze chroot and I it also fails with
the NullPointerException.
The other thing is it is probably better for the binary to depend on
default-jre instead of openjdk-6-jre as it has not been ported to all
debian architectures. However you might still have a runtime error for
the architectures that use gcj-jre as the default: [avr32, hppa,
hurd-i386, kfreebsd-amd64, kfreebsd-i386, m68k].
