Knut Anders Hatlen commented on DERBY-4805:
-------------------------------------------

InternationalConnectTest fails on Solaris now if the underlying file system is 
UFS. The problem appears to be that UFS doesn't allow path names that are 
longer than 1024 characters. The path name used in the test is shorter than 
that, but it's a relative path name, so it may get longer than 1024 characters 
after it has been canonicalized.

> 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
