    value:

"According to its self-reported version number, the installation of
Apache Derby running on the remote server performs a transformation on
passwords that removes half the bits from most of the characters
before hashing.  This leads to a large number of hash collisions,
letting passwords be easily brute-forced.  This vulnerability only
affects the BUILTIN authentication method. 

Note that Nessus has not tested for the issue but has instead relied
only on the application's self-reported version number."
