Hi All,
When File.createTempFile() is called with some special parameters, it
runs into infiniteloop and hangs. It is because it does not always
mean a file exists when the method, createFileExclusively(), returns
false. This fix is going to solve such issues reported in JDK-8013827
and JDK-8011950.And I also added some testcases to verify it.

Thanks for taking this one.
The changes mean that IAE is now thrown for cases where it wasn't thrown
previously and I'm wondering if this is worth doing. It might be simpler
to just throw IOException on the grounds that creating the file will fail.
One other thing to consider is that "\" is a valid name of a file on
some platforms. I suspect you'll need to delegate to the FileSystem to
check the suffix/prefix. Alternatively in TempDirectory.generateFile you
could create a File from prefix/n/suffix and call getName to check that
its matches. If not then throw an exception.
