Whenever I create a folder under WebContent in Eclipse Luna, this pops up even though the folder gets created.

enter image description here

The message is:

Problem Occured

'Refreshing Process Information' has encountered a problem.

An internal error occurred during: "Refreshing Process Information".

An internal error occurred during: "Refreshing Process Information".
  java.lang.NullPointerException

Why the java.lang.NullPointerException?

EDIT:

Attached Error Log:

enter image description here These are the problems listed:

    Under Window -> Show View -> Error Log you can find more information. Please post that as well here. – David ten Hove Dec 01 '14 at 12:55
  • Your pictures are too small to read. Also, you can get some detailed info if you double click on one of the lines in the error log. – David ten Hove Dec 01 '14 at 13:29
  • @David ten Hove: Exception stack trace shows NPE due to the JBOSS Plugin installed in Luna Eclipse. I think i should not bother about this then..It's has something to do with the internal functioning mechanism. – Farhan stands with Palestine Dec 01 '14 at 13:33

Try to delete the .metadata folder and import the project again (just to be safe, make a copy of your project folder somewhere else.)

And are you using GIT in your project ?

Even though it was the old post, this answer will helpful for someone.

Try to close and open the project, refreshed project get fixed the NullPointerException in my case.

Even though error is not getting fixed, close the project -> close eclipse -> open eclipse -> open project may fix your NullPointerException.
