Attila Kelemen commented on NETBEANS-698:
-----------------------------------------
It seems that the issue is that there is an "assert" there in NB and
assertation is enabled by default in NB 9 (I would guess that this issue would
have happened in earlier versions of NB as well, if assertations were enabled).
I haven't check this at great enough detail yet, but if I remember correctly,
the URL will end with a slash if the classpath entry exists at the time of
loading the project. In this particular case I could make sure that this path
ends with a slash (since I happen to know that the build output directory is
... well ... a directory) but it seems a little fragile since there could be
all kinds of things on the class path. Especially now, since the ".jar" files
should be returned for the sources as well. That said, "file" URLs ought to be
directories on the class path (because jars have the "jar" scheme), so I will
review how these URLs are actually created.
A trivial workaround is to remove the "-J-ea" from netbeans.conf.
