I was opening a new project and selected Java EE. Then after it activated and opened I saw this error.
Comment 3 matthias42 2015-11-25 20:35:59 UTC 
The exception you are seeing is caused when the sample db can't be created. There are two valid states:

a) The sample derby db already exists and is valid
b) The target directory for the DB is either empty or does not yet exist

In your case the third state is reached: the directory exists but is not empty.

Could you please take a look at the referenced directories and list the contents?

C:\Users\jyeary\.netbeans-derby\sample

and

C:\Users\mbutler\.netbeans-derby\sample

There might be some garbage from an old db - I'm thinking about adding a dialog to ask the user what to do in this case, but before I'd like to know what makes the code stumble. Thanks for your help!

In my case it occurred when starting to use 8.1 (before that, I had been using its "dev" builds for months already). After this exception came up, I simply deleted the folder (partly because of this error, partly because I hate seeing directories like that in my user directory (cf. bug 207507)), so I can't help.
Comment 5 matthias42 2015-12-04 21:16:09 UTC 
Thanks for replying terj7601, I decided to go ahead with the fix (to be frank the error is only logged and not reported anymore - this brings it in-line with 8.0).

The fix was pushed as:

http://hg.netbeans.org/core-main/rev/e8911c5e8884

If anybody can reproduce the problem with 8.1 please check when a nighly is build that contains this fix and mark this bug as VERIFIED.
