Digy updated LUCENENET-135:
---------------------------

    Attachment: DocumentsWriter+SupportClass.rar

Since calling Monitor.PulseAll or Monitor.Wait before Monitor.Enter results in 
SynchronizationLockException (which is the case in code after removing 
"lock(this)"es ) I chose AutoResetEvent that is most suitable for wait/notify.

I also coded a new class "SyncObject" for java's synchronized methods that 
allows nested locks of the same object in the same thread just like 
{code}
lock(this) 
{
   .....
   lock(this)
   {
      .....
   }
}
{code}

> There is a race condition in DocumentsWriter.UpdateDocument. Locking the 
> whole method solves the problem but this is not what  is intended in java 
> version
> (testcase:  Index/TestIndexWriter/TestDocumentsWriterExceptionThreads)
> I am working on it.
