Noticed a NullPointerException in the terminal when running eclipse from the command prompt. I had just been editing a java source file... The exception appears to have had no functional impact on Eclipse. The stack trace is as follows: java.lang.NullPointerException at org.eclipse.wst.xsd.ui.internal.adt.editor.ADTMultiPageEditor$InternalLayout.layout(ADTMultiPageEditor.java:90) at

The exception still occurs with Eclipse SDK 4.4.0.20140612-050 And it does have a functional impact : not able to edit an XSD file (see screenshot).

(In reply to Emmanuel Guiton from comment #2) > The exception still occurs with Eclipse SDK 4.4.0.20140612-050 > And it does have a functional impact : not able to edit an XSD file (see > screenshot). I'm also unable to edit an XSD file and in the logs there is this exception. Eclipse Java EE IDE for Web Developers. Version: Luna Service Release 1 (4.4.1) Build id: 20140925-1800 Can I suggest to change "Importance: P3 minor" to something more appropriate?
I am seeing the exact same traceback stack as shown in comment #3. This is occuring while running a Junit test on an Activiti Maven project. The relevant Eclipse build is 4.4.2.M20150204-1700.
It's possible to open only one xsd file in an editor at the same time. Trying to open a new one ends up with the exception as in above comments. When I close the previously openned xsd file and then try to open the one that failed it will open successfully. To open another one, I have to close the one already openned. Other editors work fine at the same time. When I restart the IDE it works fine for a while (non-deterministic). Spring Tool Suite Version: 3.7.1.RELEASE Build Id: 201510041210 Platform: Eclipse Luna SR2 (4.4.2)
