[Bug 294753] Re: ImageJ chooses wrong java home

[Peter Husen]

No it's not fixed. The line that determines the java home is still the
same:
  JAVA_HOME=$(/usr/sbin/update-java-alternatives -l | head -1 | cut -d'
' -f 3)
i.e. still the first line from update-java-alternatives -l, which is not
necessarily the configured alternative. I just installed 1.43b-1 by
installing ia32-sun-java6-bin, and it still fails in the way I
originally described (with the message "Running a 64-bit JVM is not
supported on this platform."), since it (wrongly) chooses the 32-bit jvm
and tries to use it in 64-bit mode.

$ update-alternatives --display java
java - status is manual.

Current `best' version is /usr/lib/jvm/java-6-openjdk/jre/bin/java.

$ update-java-alternatives -l
ia32-java-6-sun 63 /usr/lib/jvm/ia32-java-6-sun
java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk
java-6-sun 63 /usr/lib/jvm/java-6-sun
java-gcj 1042 /usr/lib/jvm/java-gcj

Notice how the first item in the latter output does not match the
currently configured java alternative.
