made ProductDerivations a bit more fault-tolerant -- when a failure occurs while loading ProductDerivation instances defined in services files, the system continues to start up with the ProductDerivations that did load, and a warning is printed to stderr. Note that this means that people using the uber-jar in 1.3 or 1.4 environments, or without having javax.persistence in their classpath, for example, will see warnings on stderr.

no-product-derivations: Your system is missing product derivations. Product \
derivations provide configuration options for supported data stores and \
specifications. You must have a META-INF/services/{0} file in your \
classpath listing the available derivation classes, and some listed class \
must be instantiable. Typically this file is bundled as part of the \
distribution. Have you unbundled it, or unbundled its listed classes? \
If you are using ant, a common solution to this problem is to place \
the jar libraries of the OpenJPA distribution in the \
$'{user.home}/.ant/lib directory. Another common cause of this problem \
is an overly-restrictive security manager.
