Eclipse gets "IWAB0014E Unexpected exception occurred." when I'm trying create a soap client

Question

I'm trying to create a soap web service client and when I go to File > New > Other > WebServices > WebServiceClient.

I'm getting this error:

IWAB0014E Unexpected exception occurred.

I'm using Eclipse 2019.09 and apache cxf2.x V3.3.5 and GlassFish 5.0.1 and jdk 8. I added apache runtime to Eclipse's preferences. I searched allot and none of existing solutions solved my problem. Thanks in advance.

This looks like [Eclipse bug 288912](https://bugs.eclipse.org/bugs/show_bug.cgi?id=288912). — howlger, Jan 21 '20 at 09:02
That's Null pointer exception, but this is loader constraint violation. — hamidreza75, Jan 21 '20 at 15:19
Sure, but the `IWAB0014E Unexpected exception occurred.` error happen in both cases in the same situation at allmost the same location (`org.eclipse.wst.command.internal.env.core.fragment.CommandFragmentEngine.runCommand`), which might be caused by different versions (by the way, is there a reason why you are using an outdated Eclipse version?). However, the solution for an issue found in open source software is to make sure it has been reported and to help to fix it. Up to now, the bug has no votes and has only been confirmed by three people in 10 years. — howlger, Jan 21 '20 at 17:13
So, congratulations to the almost successful creation of a SOAP web service client with _"eclipse 2019.09"_ (which is almost the right term for _Eclipse 2019-09_). — howlger, Jan 21 '20 at 19:29

I downloaded the latest version of Eclipse and that error disappeared! Eclipse IDE for Enterprise Java Developers.

Version: 2019-12 (4.14.0) I recommend clean install rather than update.
