The plot thickens. The above command works. However, typing
'dicomscope' doesn't. /u/b/dicomscope is a symlink to the jar file,
not a script, so I guess binfmt is at play.
It seems the binfmt support is failing at some point.
% readlink -f /usr/share/binfmts/jar
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/jar.binfmt
% cat /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/jar.binfmt
package openjdk-7
interpreter /usr/bin/jexec
magic PK\x03\x04
But I can't get to run jexec directly:
% readlink -f /usr/bin/jexec
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/jexec
% jexec
can't locate java: No such file or directory
