Build: NetBeans IDE Dev (Build 201509030002)

OS: Windows 7

User Comments:
ytn01: I was debugging a WebProject, and a breakpoint was hit.

Same time, I went to plugins manager window and Installed easyUML plugin from downloaded nbm files. After installation I clicked "Yes" on the "restart IDE" prompt.

After IDE restarted, I "New Project" toolbar icon, selected UML category -> UML Diagrams Project, and clicked next.

Gave project a name, and clicked finish.

Then exception was generated.

wontfix in NetBeans.

please file against the owner of easy uml. it's dependency on projectuiapi has to be updated.
until then it won't work with the current state in trunk.

I'm getting the same error for the Scala and SBT Project plugins.  The class appears to be the same in the API documentation.  When you say, "it's dependency on projectuiapi has to be updated." is that just a recompile or how it should use that class has changed?  Is there documentation as to best practices for updating a 8.0 plugin to 8.1?  Maybe I can help?
