I am using GWT 2, GAE 1.3.0 plugin on Eclipse Galileo. I have a class UtilJDO, which does not contain any persistent object. It merely pulls in the pm, pmf, and provide common methods for queries.
My persistence classes extend UtilJDO so that they could all use the same utilities. Whenever I modify UtilJDO, without making modification to any persistence classes that extends it, development server at runtime croaks that it appears my persistence classes have not been enhanced and my queries, updates fail. To overcome this, I edit one of those persistence classes by introducing an insignificant space character and then saving it. Then datanucleaus reports 11 classes enhanced and my problem solved. Therefore, this is certainly a bug, isn't it? I mean, datanucleaus designers did not seem to have expected me to create persistent subclasses by extending a non-persistent class.
