Christian Lenz commented on NETBEANS-1864:
------------------------------------------
Please give some more info about that. Why is the "background scanning got
stucks" related to the linked Exception ticket? Does it make more sense that it
is related to NETBEANS-168? Please give steps to reproduce too.
