Description soldatov 2012-02-07 08:39:32 UTC 
a lot of tests fails with such exceptions:

Comment 2 Vladimir Voskresensky 2012-02-07 08:57:39 UTC 
very strange how file test3_testLinesBeforeFunction.h
 with extension can be passed to sniffy resolver

I will add diagnostic to find problematic resolver
Comment 3 Vladimir Voskresensky 2012-02-07 09:00:03 UTC 
more logging

Comment 4 soldatov 2012-02-08 07:54:09 UTC 
New line is

Comment 7 Vladimir Voskresensky 2012-02-08 09:24:50 UTC 
Thanks!
Comment 8 Vladimir Voskresensky 2012-02-08 09:52:15 UTC 
saveFromKitToStream is called from 
CloneableEditorSupport$1SaveAsReader.run(CloneableEditorSupport.java:1079)
and previous operation is 
os = new BufferedOutputStream(cesEnv().outputStream());
which write-lock environment/fileobject 
=> 
nobody can call getMimeType for file object associated with document from 
saveFromKitToStream
which looks like very strong restriction.
Comment 9 Vladimir Voskresensky 2012-02-08 11:13:11 UTC 
another issue:
mix of annotation based registration and layer based registrations causes incorrect ordering of resolvers
