Getting a word from the lexicon, then adding a feature, causes that feature to be present if the same word is then got from the lexicon again.

[GoogleCodeExporter]

WordElement tree1 = lexicon.getWord("tree");
System.out.println(realiser.realise(tree1));  // tree

tree1.setFeature(Feature.NUMBER, NumberAgreement.PLURAL);
System.out.println(realiser.realise(tree1)); // trees

WordElement tree2 = lexicon.getWord("tree");
System.out.println(realiser.realise(tree2)); // trees

The solution would be to make a copy of the word when retrieving from the 
lexicon, rather than use the original. Note that this isn't picked up in the 
unit tests because the lexicon is created fresh for each test, rather than 
recycled.
