Subject Request to add new runtime exception in openjpa-lib subproject for error control in bootstrap process
Date Wed, 18 Jul 2007 17:41:51 GMT
Hello,
Given the dependency of exception classes in openjpa-kernel subproject
to PersistenceCapable/ImplHelper, migrating them to openjpa-lib will
require non-trivial changes. 
Instead, proposed to add a ConfigurationException (extends
RuntimeException) in openjpa-lib subproject. Bootstrap process will
recognize this exception and abanadon bootstrapping for fatal
ConfigurationException thrown by any derivation. 

Comments?

Marc,
Dependency in openjpa-kernel goes
UserException->OpenJPAException->Exceptions->PersistenceCapable.

More surgery needed to migrate exceptions to openjpa-lib

I can't think of any reason why we couldn't do this. Provided we don't
change the package name or anything like that, swapping the module that
contains this exception stuff wouldn't result in any user- visible
changes.
