Mamta A. Satoor commented on DERBY-4805:
----------------------------------------

Hi Knut, thanks for fixing the problem by putting the / in the jdbc url(and taking an 'a'
out from the dbname to make sure that we are still at 1024 limit for positive test and at
1025 for negative test) to make it absolute path. I made the changes on my Windows machine
and the test ran fine. I will go ahead and commit the changes. Thanks again.

> Currently, whenever the client driver is used, there is a limit of 255 bytes for the
database name. This is defined by the DRDA spec and there has been a discussion on the list
[1]/[2] as to whether this limit should be raised due to the introduction of the new ACR that
allows for UTF-8 characters.
> UTF-8 characters can take up to four bytes and this reduces the limit in characters dramatically.
> This should be an easy change as there is a codepoint that defines this limit.
> [1] did not work but [2] did
