Description Rochelle Raccah 2002-01-03 04:59:21 UTC 
This is related to some changes Yarda made a long time ago described in issue
8462.  When the automatic file recognition triggering event is the addition of
the other file, the following exception is seen:

Yarda, your opinions?
Comment 2 Jaroslav Tulach 2002-01-03 08:24:14 UTC 
I remember Petr Hamernik trying to fix similar bug by catching
UnsuppOpEx on line 658, he probably has to catch the exception in this
place too or rewrite the code not to use unmodifiable collection at
all.
Comment 3 phamernik 2002-01-03 15:51:02 UTC 
This bug is a duplicate of #18785. It is regression caused by bugfix
#12136 (2001/12/13). Radek Matous and me are looking at it.
