[ptp-dev] Problems with null pointer exceptions in PTP 2.0 RSEFileSystem

[Dave Wootton <dwootton@xxxxxxxxxx>]

I'm trying to run my PTP 2.0 plugins
on AIX and am having problems with lots of null pointer exceptions when
filling in a launch configuration that I'm not seeing on Linux  that
have the following few methods at the top of the traceback
java.lang.NullPointerException

org.eclipse.core.internal.filesystem.NullFileSystem.getStore(NullFileSystem.java:52)

I downloaded the PTP code from CVS using
the PTP 2.0 tag to try to debug this. It looks like the reason I'm getting
the null pointer exception is because there's a call to RSEFileManager.toURI
where a URISyntaxException is caught and that method returns null. The
IPath object that's passed to toURI has a device=null and a segments array
with a single String element with value pmadjpri.log. 
The detail message in the URISyntaxException
is "Relative path in absolute
URI". The input variable in
the URIException object is rse://K17SF2P01.PPD.POK.IBM.COMpmadjpri.log

Is this exception being thrown because
of something missing out of the pathname (it looks like '/' or ':' might
be missing)?

Note: The pmadjpri.log is passed in
as a String parameter (path name) to my method org.eclipse.ptp.rm.ibm.pe.ui.PERMLaunchConfigurationDynamicTab.validateOutputPath
at line 2740 where I'm trying to validate a pathname on the remote system.
Am I doing something invalid in that method?
