Re: [Exist-open] can't delete collection with long name

[Mike S. <so...@if...>]

The error deleting a long-named collection is ultimately caused by:

java.io.IOException: Cannot make collection filesystem directory:

I guess maybe the length is the problem; the filesystem won't allow such 
long filenames.  So it seems that the filesystem limits should be taken 
into account when choosing the proper limit for collection name length.

It is however possible to rename the collection and then delete it.
