#16 Display mark if method is invoked in a synchronized block

[Ola Mattsson]

Hi,
I think it would be very useful if one could display the
call hierarchy of a method with special markers for the
calling methods that invokes "this" method inside a
synchronized block. Just like the marker that is displayed
if a calling method itself is synchronized.

Even better would be if one could easily see which
object the block is synchronized on. This would expose
potential threadproblems.
