StickyScrolling: Exceptions while opening Java editors from Search view

[iloveeclipse]

I've searched for method references and used Search view to navigate ("reuse editors" was on, "sticky lines" limit set to 4).
Sooner or later I've got following exceptions below trying to open next search result in Java editor

Probably regression from #2592

[iloveeclipse]

@Christopher-Hermann , @BeckerWdf : could you please check?

[iloveeclipse]

Steps to reproduce for me are:

1. search for org.eclipse.jdt.core.IPackageFragmentRoot.getRawClasspathEntry()
2. open first match org.eclipse.jdt.core.JavaCore.getGeneratedResources(IRegion, boolean)
3. open second match org.eclipse.jdt.internal.core.CopyPackageFragmentRootOperation.executeOperation()
4. Error logged

[iloveeclipse]

I observe now worse behavior:

1. Sticky scrolling isn't shown in most of the cases at all (no errors, just nothing). Simply use same reproduction steps as before. It looks like the very first open can't show sticky area and from there on it is not shown for all other editors opened from the "search" view too.
2. Sometimes it is shown (seems that it works for editors opened from package Explorer)
3. Still see the error below, but now it can be reproduced not as often as before. Still, clicking on different matches in the Search view back and forth can reproduce same error:
