Comment 2 Jan Lahoda 2010-10-04 08:03:14 UTC 
The problematic place is probably:
return Lookup.getDefault().lookup(SPI.class).<method-invocation>

Most likely Lookup.getDefault().lookup(SPI.class) returns null. But, the implementation of the SPI (SPIImpl) is a nested class of Utilities itself. No idea why it was not found, but there are more suspicious exceptions in the log, e.g.:
org.netbeans.modules.java.editor.semantic.MethodExitDetector
could also not be found. From this, it seems like some problem with classloading, possibly related to bug #166236.

Your guess is as good as mine. IDE looks corrupted somehow.
