ClassCastException trying to create EJB Project [message #77704]

Did a clean install of Eclipse M5 and WTP M3. Trying to create a new EJB
Project gives me following stack trace. This stack trace occurs when you
choose 2.0 as the specification version but not when you choose 2.1.
Also after the stack trace has occured whenever i try to type something
to the name field of the ejb project wizard my characters are doubled
(eg. "TestProject" becomes TTeessttPPrroojjeecctt").

Janne,

For EJB 2.0 project creation you need
http://www.eclipse.org/webtools/wst/components/ws/download_i nstructions_for_jars.html.
Although the build page says these jars are optional to enable web
services, it required for ejb 2.0 project creation. I have tried it both
without and with these jars and I see the same problem that you are
seing without these jars but once have the web services jars things are
working fine. We will look more into this issue in M4 to remove this
dependency.
