Exception raised during RPF data loading #8

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Environment:
- OpenMap version: 5.0.3
- Operating System: Microsoft Windows XP

Issue description:
The loading of RPF data with [OpenMap] demonstrator leads to an exception (see 
further in the issue).
This problem does not occur with the version 5.0 of [OpenMap].
The exception is not raised anymore when the 
com.bbn.openmap.layer.rpf.RpfProductInfo class available in the version 5.0.3 
is replaced by the one delivered in the version 5.0.

Exception:

As far as I see not fixed yet. The static intializer should not try to add 
instances of its own class to the map (a bit too early ;). The lazy loading as 
seen in 4.6.5 is doing fine.

Hmm, the static initializer by itself seems to be ok. The initializing as seen 
in the stack trace above introduces the problem.
I'll work around it by calling a dummy
RpfProductInfo.getCatalog();
prior to any use of this class.
