Good idea! I wonder if this should be done as a unit test.  go through all the bundles and check leading/trailing whitespace.

in my experience, the translators also (unintentionally) change the quotes and other symbols, sometimes breaking the code.  I assume the JDK has been exhaustively tested and we have no such problems.
