[ecf-dev] R-OSGi NullPointerException

[Martin Petzold <mpetzold@xxxxxxx>]

Hi folks,

I use ECF (3.4.0.v20101029-1626) and R-OSGi as distribution provider and 
start two instances of my node component (each an osgi instance) on THE 
SAME machine quickly after each other. I get the following Exception. If 
I wait about perhaps 10sec. there is no problem.

!ENTRY org.eclipse.osgi 4 0 2010-11-25 16:36:14.600
!MESSAGE An unexpected runtime error has occurred.
