From Hibernate 4.3.0Final, the location of the C3P0ConnectionProvider has changed from
org.hibernate.service.jdbc.connections.internal
to
org.hibernate.c3p0.internal
Please can you do one of the following as resolution
a) update EncryptedPasswordC3P0ConnectionProvider to use the updated location
b) release a modified version for 4.3.x only
c) add a property that could be set to override the default location
d) another resolution that solves the issue that I didnt think of :)
