XtendHoverInEditorTest broke

[cdietrich]

XtendHoverInEditorTest does no longer work.

TODO: check what in platform or jface or jdt has changed

@iloveeclipse is there anything that comes to your mind?

the info the test gets seems to null now

[iloveeclipse]

Link to test failure?
Since when it is failing?

I assume test code is https://github.com/eclipse-xtext/xtext/blob/main/org.eclipse.xtend.ide.tests/xtend-gen/org/eclipse/xtend/ide/tests/hover/XtendHoverInEditorTest.java

[cdietrich]

its the xtend file of that.
it started failing with the ibuilds available on dec. 19th

https://ci.eclipse.org/xtext/job/xtext/job/main/2618/

[cdietrich]

i believe in older versions
org.eclipse.xtext.xbase.ui.hover.JavaDebugHoverProvider.getInformationControlCreatorProvider(ITextViewer, IRegion)
would give the results.
but i dont have dev enves for olders available to test

[iloveeclipse]

Just to be clear: all other failing tests were failing before, or they are also started to fail at same time?

[cdietrich]

the others are known to be flaky.
and noone has capacity to investigate

[iloveeclipse]

eclipse-jdt/eclipse.jdt.ui@aa34e37 ?

[cdietrich]

#3376

[iloveeclipse]

Or eclipse-jdt/eclipse.jdt.core@b0135c9 , or both?
If Xtext test depends on some JDT links parsing.

[cdietrich]

hmmm i-builds seems to be light years behind.
pde shows me 20251204

but i also have no proper dev env to debug for the next weeks. on mac it also fails in 202512

[cdietrich]

attempt to build in ci against 202512: https://ci.eclipse.org/xtext/job/xtext/job/main/2623/

[cdietrich]

org.eclipse.xtext.common.types.xtext.ui.JdtHoverProvider.getHoverInfo(EObject, ITextViewer, IRegion)
is the place where we get different results...

some are cause by the html produced seems to have newlines now

[cdietrich]

Class <code>Object
 </code> is the root of the class hierarchy.

am not sure if that newline is intended

[iloveeclipse]

eclipse-jdt/eclipse.jdt.ui#2685 is likely related.

[iloveeclipse]

See eclipse-jdt/eclipse.jdt.ui#2693

[iloveeclipse]

eclipse-jdt/eclipse.jdt.core#4686 is supposed to be the fix
