What does “no method return value” mean in Eclipse Debug perspective?
Placing a breakpoint in a method which is run by multiple threads, I encountered for the first time a "no method return value" Name in the Variables tab:
What does it mean?
Acting, breakpoints in other places behave normally and do not produce this message.
Why am I seeing this?
UPDATE:
I found the answer for "Why I am seeing this?":
As I clarified in the comment below, the aforementioned method does return a value. However, it is static and despite clean build of the entire project building it, I could not get rid of that weird "no method return value" thing.
Only after I did clean build of all projects in my workspace, did this message disappear and was replaced by the normal variables names and values display.
Any answer that could explain why an entire workspace clean build is mandated and why "no method return value" instead of some other (more descriptive) message, will be accepted.

Normally Eclipse would show the value returned by that function call, but it has none.

@tobias_k Weird. That method in which I placed a breakpoint does return a value (int), but for some reason, I am unable to view any of the variables in that method (I can only viewthis). Could this be related to the fact that this method is being called by numerous threads running concurrently?

The Variables view shows the variable of the in the Debug view selected stack trace item. Different threads have different stack traces which are shown as separate subtrees in the Debug view.
