NoSuchMethodError when using Eclipse 4.2 [message #924945]

Hello Jubula-Forum,

we updated our RCP application to use Eclipse 4.2 instead of Eclipse Indigo.

Unfortunately, testing our application with Jubula is not possible any more. Simple actions like choosing entries from the menu bar fail, since Jubula does not recognize any new open sub menu (ub_mbr_selectEntry_byTextpath for "Window/Open Perspective/Other..." fails with the action error "The submenu for 'Window' did not appear". Nevertheless, that submenu was visible after the successful performed mouse click to the menu entry "Window").

Also, when performing some manual tests for different actions (in general actions causing a new editor tab to be opened) an error message appears. The corresponding log entries are similar to the following:

java.lang.NoSuchMethodError: org.eclipse.ui.internal.PartPane.getToolBar()Lorg/eclipse/swt/widgets/Control;
at org.eclipse.jubula.rc.rcp.accessor.Startup$PartNamingListener.partOpened(Startup.java:465)
...

Searching the bug database I found for example bug 379217 (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=379217). It seems the problem occurred due to the usage of internal Eclipse APIs by Jubula not available in Eclipse Juno any more. Unfortunately I could not find any comment about a fix in Jubula or whether the problem will be fixed. Is it possible to say whether this issue will be fixed and when? Are there any workarounds to the problem?

Best regards,
Michael Werter

There are a few problems when using Jubula with 4.2. Menus don't work at the moment due to a bug in e4 event propagation. This should be fixed with Juno SR1. There are probably more problems which we haven't found/addressed because the menu bug stopped most of our regression tests.

There will be some work on e4, especially w/o compatibility layer, starting in the near future. Feel free to enter Bugzilla entries for every problem you find.

Hello Achim,

thank you very much for your quick response.
Does this mean the problems will be fixed due to changes in Eclipse, but not due to changes in Jubula? This would mean, to get the Jubula tests working again, an update of our application to Juno SR1 is mandatory?

Kind regards,
Michael Werter

The menu problem is caused by an e4 problem. It should go away when the AUT is updated to SR1. Other problems might lurk because we haven't tested e4 extensively. Native e4 is not supported at all at the moment because we can't get at the necessary information for tests without some work on the internals of Jubula RC.
