I no longer pull down masters because the releases have been working for me. The documentation says I should be able to upgrade from beta versions to newer releases. This latest problem happened even when I was trying to go from 1.2.0.Beta3 to 1.2.0.Final. Since that did not work, I waited a while hoping a later version would improve the situation. People often do what they are not supposed to. Expecting people to only upgrade from Final release to Final release seems like wishful thinking and may lead to unhappy customers, even if they are wrong.
