I closed Eclipse while working on some files shared via Windows file share. The next day I came back and reopened the files (the file share had since gone offline). All of my editor windows came up with:

java.lang.NullPointerException

What kind of files did you open? Does the problem occur with simple .txt files?

A lot of Coldfusion (.cfm) files with CFEclipse (so maybe this is their problem?). The internal fileshare is back up, and I'll get in lots and lots of trouble if I take it down to retest this, so it's hard to recheck with .txt files, sorry. :/

The NPE is caused by CFEclipse. Please report your bug there.
