There are several problems with the java plugin:

1) It tries to find java_vm in my $HOME/bin instead  of its proper location
   and crashes Mozilla if it can't find it.

2) It looks for files at $HOME/lib/i386 directory and crashes Mozilla if it    
   can't find it.

3) It looks at $HOME/lib/plugin.jar file and crashes Mozilla if it can't find i
   it.

Obviously it should look for these files in /usr/j2se instead.

Once I got past these it crashes. Here is a part of truss output:
