array bounds error in mdui:IPHint validator

[iay]

An <mdui:IPHint> value of (say) "1.2.3.4", lacking a "/nn" mask size component, results in an array index out of bounds error.

This is due to a java-support issue.

We need a fix for this until the underlying issue is resolved. The fix can be removed in the 0.9 branch once java-support has been corrected.

This is now fixed in the version of the java-support library to be included with MDA 0.9.0.

Fixed on the 0.8 branch by commit 13a1338. Still to be addressed on the 0.9 branch. Although the java-support library has been fixed, I'd like to make sure I have a test for this issue in the branch even if we don't need the workaround.
