Hi Christian,
It's related to Bug 511888
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=511888 >.
Is Synchronization a good solution to this problem? However I read it comes
with several problems. One includes possibility of performance reduction
and second creation of deadlocks. Will these two cases be relevant in this
type of code?

Hi Prashanth,
There are two ways to go about solving a problem like Bug 511888, add
synchronization or redesign the code to not need it.
It is true that synchronization has a performance penalty, but unless
you have profiled the code to demonstrate it is critical performance
wise it is not likely a problem. Deadlock is always a problem to worry
about, but more research into this case will determine if it is a
problem here.
My suspicion is that what is missing is a way to synchronize the read
of the list in org.eclipse.ease.ui.view.ModuleStackDropin$2. getElements(ModuleStackDropin. java:92).
In otherwords are there many writers, or just one. That will determine
the strategy for solving the problem.
HTH
Jonah
