> With Java 7 we now must handle either NoSuchFileException (thrown by nio) or
> FileNotFoundException (thrown by pre-nio io apis) coming out of some
> Directory methods.
> We did this on trunk already but we need to do it for 4.x as well...
> including fixing MockDirWrapper to randomly pick one to throw.
> Uwe said:
> I did a grep for NoSuchFileException on trunk and 4.x.
> In trunk we have many more of this Excepotion, especially also randomization
> in MockDirectory to throw this one or FNFE. We should backport those fixes:
