Description Peter Most 2015-10-19 06:03:42 EDT

I've entered a manual proxy configuration without "Proxy bypass" entries which resulted in a eclipse/configuration/.settings/org.eclipse.core.net.pref:

eclipse.preferences.version=1
org.eclipse.core.net.hasMigrated=true
proxiesEnabled=true
proxyData/HTTP/hasAuth=true
proxyData/HTTP/host=proxy-emea.rsint.net
proxyData/HTTP/port=80
proxyData/HTTPS/hasAuth=true
proxyData/HTTPS/host=proxy-emea.rsint.net
proxyData/HTTPS/port=80
systemProxiesEnabled=false

Note the missing 'nonProxiedHosts' entry! At first this seems to work and I can access the marketplace for example. But after some time it stops working. I wasn't able to determine when this happens. When I then try to open the 'Network Connection' settings this leads to a NullPointerException:

eclipse.buildId=4.5.1.M20150904-0015
java.version=1.8.0_60

BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.java.product
Command-line arguments:  -os win32 -ws win32 -arch x86 -product org.eclipse.epp.package.java.product

When I manually added the line:
nonProxiedHosts=localhost

then this error went away.
