Description Todd Allen

2015-12-22 16:13:48 EST

Each time I try to create a new class I get no response.  The "Finish" button is active and not grayed out.  I enter the class name and click the "Finish" button but nothing happens.  This happened on the Juno release and still happens after upgrading to Luna.  The .log file indicates a NullPointerException.  Stack trace:

Works for me using plain 4.5.1:
http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.1-201509040015/

I suspect it's the same issue as bug 244770.

I looked at bug 244770.  It looks similar but not the same.  The PHPEclipse plugin was installed and has been removed. The problem persists. The same stack trace is in the .log file.

Version: Luna Service Release 2 (4.4.2)
Build id: 20150219-0600

Sorry, but Luna is no longer supported. Please take
http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.1-201509040015/
and if you can reproduce with that and a new workspace reopen with detailed steps.
