Re: [Exist-open] Document names longer than filesystem names- backups fail

Well it is Java's goal to be a cross platform system not my own, of
course eXist also aim's for cross platform compatibility through Java. 

For this they (Java implementers) must ensure that a Java function is
consistent across platforms. How they achieve this is not my concern
(unless they do not achieve that, like in this case). Whatever the
solution, the question is should that solution be applied to the JVM or
eXist. I believe that the problem is in the JVM and it would appear that
the Java guys are also looking for a better way to achieve this in Java
7. So perhaps they and I agree here?
