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

[Manny Vindiola]

Package: imagej
Version: 1.43g-1
Severity: important
Tags: patch

When java-gcj-compat is the only java version installed on the system the application will not run. It fails with message /usr/bin/imagej: line 420: //bin/java: No such file or directory. This is because of the JAVA_HOME hack introduced inversion 1.43b-1.

When the correct path is specified it still will not run. It crashes with error:
(lucid32)manny at laptop:~/dev/submitted/imagej$ imagej     
Open other images in this ImageJ panel as follows:       
  imagej -p 1 <image1> [<image2> ... <imageN>]           

Exception in thread "main" java.lang.NullPointerException
   at java.awt.Component.setDropTarget(libgcj.so.10)     
   at ij.plugin.DragAndDrop.run(DragAndDrop.java:28)     
   at ij.IJ.runPlugIn(IJ.java:152)                       
   at ij.IJ.runPlugIn(IJ.java:135)                       
   at ij.ImageJ.<init>(ImageJ.java:184)                  
   at ij.ImageJ.main(ImageJ.java:554)        

These errors can be corrected by depending on openjdk-6-jre and reverting the JAVA_HOME hack to what it used to be. I have attached a patch to correct these problems.
