RTC 6.x and Eclipse Neon or Oxygen?

Patrick LoPresti (88●5●9) | asked Jul 07 '17, 1:40 p.m.

 I have tried installing RTC 6.0.3 and 6.0.4 from the p2 repository into Eclipse Neon (Eclipse 4.6.3) and Oxygen (4.7.1). Most things work, with one killer exception:


Window -> Preferences -> Work Items generates an error dialog with title "Could Not Accept Changes" and content "The currently displayed page contains invalid values".

In the Eclipse log, I have the following backtrace:

!STACK 0
java.lang.NoSuchMethodError: org.eclipse.ui.internal.WorkbenchWindow.getTrimManager()Lorg/eclipse/ui/internal/layout/ITrimManager;
        at com.ibm.team.workitem.ide.ui.internal.preference.WorkItemPreferencePage.isActiveWorkItemTrimVisible(WorkItemPreferencePage.java:273)
        at com.ibm.team.workitem.ide.ui.internal.preference.WorkItemPreferencePage.activeWorkitemTrim(WorkItemPreferencePage.java:166)
        at com.ibm.team.workitem.ide.ui.internal.preference.WorkItemPreferencePage.createContents(WorkItemPreferencePage.java:85)
[etc.]

Note that everything works fine with Eclipse Luna and Mars.

I am not an Eclipse expert... But based on some research (e.g. https://stackoverflow.com/q/31472140/), it appears that RTC relies on the Eclipse 3.x "compatibility layer" in Eclipse 4. Apparently, emulation for the "internal" interface org.eclipse.ui.internal.WorkbenchWindow.getTrimManager() was removed in Neon.

Are others able to reproduce this issue? Is RTC expected to work with Eclipse Neon? Are there any potential work-arounds?

Thanks.
