[ptp-dev] Hang in RemoteServicesProxy.getConnectionManager

[Dave Wootton <dwootton@xxxxxxxxxx>]

I updated to the current PTP head this
morning and I am now running into a hang on a call to RemoteServicesProxy.getConnectionManager().
I started an Eclipse runtime instance
using the debugger and suspended the main thread. I consistently get the
traceback in the attached screen capture. It looks like RSE is waiting
for an operation to complete.

The remote service I see displayed in
the preceding println call is 'Remote service is org.eclipse.ptp.remote.internal.core.RemoteServicesProxy@d0c3d5'

The method in my code where the hang
happens is the following, where I have set up currentServiceConfiguration
when my code gets an IServiceConfiguration event notification. It also
seems that service configurations, resource managers and services within
a service configuration are not always being saved in persistent storage,
since if I shut down and restart the runtime Eclipse instance these objects
aren't always restored. Finally, it seems that if I use the service configuration
preferences dialog to edit a service configuration, and there is a launch
service defined, then when I add a performance analysis service, the launch
service seems to disappear. Could this be related to the hang?

Any other ideas?
