license compatibility

[Jo]

The license of one source worries me if it is compatible with GPLv3.
On sourceforge I found only 3 projects that seem to use this source
and the GPL too. That is not a very reassuring number. But I might be
overlooking some
http://showsrc.sourceforge.net/showsrc/src/dir2/SunFileFilter.java
http://jflac.sourceforge.net/apidocs/org/kc7bfi/jflac/apps/ExtensionFileFilter.html
http://javadiff.sourceforge.net/jdiff/reports/j2se140_j2se141_docs/changes/docdiffs_javax.swing.html

The following thread is also not very reassuring from another point of
view: multiple licenses
http://groups.google.com/group/google-code-hosting/browse_thread/thread/50af2cdf4d09fa40/a4d823d3c9544c50?lnk=gst&q=license#a4d823d3c9544c50

That is another issue that prevents me from uploading the code. Again
suggestions are welcome, whether or not want to get the code.

Issue solved.

This source was a remainder of my Java-newbee stage: copy-paste an
example, wow it works, don't touch any more. But it does way too much
in a too complicated way. With my current experience I can write my
own trivial code and no longer have to obey a license.
