Re: [GSoC] About Harmony OSGi-ed
Please ignore the exception in felix. It is not really an exception at
all but a printStackTrace that will be removed by the next release.
Sorry about that :-)
Felix should still work as expected so no need to worry. The reason
why you don't see the stacktrace on sun is that their URLClassloader
doesn't toString and recreate it's urls on classloads -- which harmony
does apparently (I'd say that is a bug in harmony but that is
unrelated to the problem at hand). We work around that issue inside
felix and the stacktrace you see is only indicating this (it wasn't
supposed to be still in there - I removed it in trunk).

Karl

I was talking about a printStackTrace in felix. So using a newer
version of HDK wont change thinks. Try updating to the latest felix
trunk - that should make the output go away.
