Eclipse Kepler crashes regularly with java.net.UnknownHostException

Question

My Eclipse Kepler on Opensuse 13.1 crashes regularly (about 5 times a day). In the error log I see this:

java.net.UnknownHostException: chmalap.site: chmalap.site: Name or service not known at java.net.InetAddress.getLocalHost(InetAddress.java:1473)

chmalap is the hostname of my pc on our local network... but why is he trying to look this up? My Eclipse is quite recent (8.2.1 and I didn't configure much settings. I have EGit and SVN plugins installed. Any ideas?

Here is the full crash information

EDIT: At the suggestion of Greg-449, I deactivated RSE UI... yet my eclipse just crashed again. This time only these errors were present in the error log (they were already present in the error log before; but always before the crash; it didn't seem to me they were present at the moment of the crash)

just to be on the safe side I removed one of each of these shortcuts since I don't use them... but they don't seem to be the critical errors to me

Answer 1

This appears to be Eclipse RSE (Remote System Explorer) doing some initialization but running in to a problem with InetAddress.getLocalHost.

If you are not using RSE you should be able to stop this initialization by going to Preferences > General > Startup and Shutdown . Uncheck the RSE UI check box, this should stop the RSE initialization from running during Eclipse start up.

Update: It looks like this might be Eclipse bug 323606 . The bug report says it caused by:

Initialize system using DHCP and don't register ip address/hostname with DNS
