When trying to create/use a ZipEntryContext on a zip file whose absolute path contains '+' symbols, the createZipSource() throws an exception looking something like:

Here's my understanding of the source of the problem, based on some debugging & research.
ZipEntryContext uses URLDecoder.decode() (via VFSUtils.decode()) to convert a file path (which may contain quoted characters, e.g. %20)  into a path that the single-String-arg File constructor understands.   In the example above, the result is '/var/folders/JG/JGDYgcyPGF8WRpvalJeL0k   TI/-Tmp-/slsb.jar', which is obviously incorrect.

I think using URLDecoder.decode() is a faulty strategy.   I'll attach my suggested fix.


(This problem would especially cause problems for OS X users, since the OS X temp directory (always? often?) contains '+++' in its path.  This is the case in the stacktrace above.  A workaround for this particular problem is to use -Djava.io.tmpdir=/some/path/without/pluses)
