resource exists with a different case: '/ttt/Test.txt'. More information:
This is because the file system does not allow this. We are reporting a file system error
We will get an exception in .log file, can we make a check before moving? I am afraid that throwing an exception is not good
We could certainly test for this before we do it.
"As per http://wiki.eclipse.org/Platform_UI/Bug_Triage_Change_2009"
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
