Hi,
sorry I missed previous mails about this. I should need a deeper look
but indeed "ClassLoader.getSystemResource"
will load in wrong location for you. It gonna search within the virtual
directory of the jar file, not in the other jar files set in the classpath.


I do not know how to search within an other jar, but if issue is only an
icon matter, the package could copy the
/usr/share/fastqc/Templates/Icons directory (from Templates in fact) in
the package structure. This is a duplication but not a big deal for a
few icons (and no security issue).
