Description Missing name

2010-08-25 08:48:15 EDT

Build Identifier: RSE Core Version: 3.2.0.v201005221100-7a7FFMRFC7sRd_SMeDdXwc Build id: 3.2 (20100607-1030)

Receive the following error in the .log file when initializing the Eclipse environment:
!ENTRY org.eclipse.rse.core 4 0 2010-08-23 14:52:44.844
!MESSAGE Unexpected Exception
!STACK 0

	at org.eclipse.core.internal.jobs.Worker.run(Unknown Source)

Note that DHCP is used to generate machines IP address and the IP address/hostname is not registered with the DNS.
The "error" does not seem to cause any runtime issues with the RSE code.

I believe that the error message should be turned into a warning since it does have any runtime issues.

Reproducible: Always

Steps to Reproduce:
1. Initialize system using DHCP and don't register ip address/hostname with DNS
2. Start eclipse
3. Open .log file and error message will be present.
