Hey guys,

I just noticed here
http://repo1.maven.org/maven2/org/hibernate/hibernate-c3p0/4.2.0.Final/

that Hibernate is still using c3p0/c3p0/0.9.1

And you made the release on 19th of March.

However there has been a newer version of c3p0 just two months old:
com/mchange/c3p0/0.9.2

Is there any specific reason to stick with 0.9.1? If not do you plan to upgrade?

OK,

to make it even more interesting, they have released 0.9.2.1 on 27th of march. And from time to time my code throws the "java.sql.SQLException: You can't operate on a closed Connection!!!" error, so I read this could be c3p0 issue dropping the connection. So I wanted to test the new versions.

I tried to update to the latest version but, of course it didn't work. Instead I got the exception bellow:

Code:
Caused by:
javax.naming.NamingException: com.mchange.v2.c3p0.WrapperConnectionPoolDataSource; local class incompatible: stream classdesc serialVersionUID = -7086951306718003710, local class serialVersionUID = 7806429541739165290
   at org.eclipse.jetty.jndi.NamingContext.lookup(NamingContext.java:485)
   at org.eclipse.jetty.jndi.local.localContextRoot.lookup(localContextRoot.java:521)
   at org.eclipse.jetty.jndi.local.localContextRoot.lookup(localContextRoot.java:536)
   at javax.naming.InitialContext.lookup(InitialContext.java:411)
   at org.springframework.jndi.JndiTemplate$1.doInContext(JndiTemplate.java:154)


I think the only artifact that needs to be updated is the http://repo1.maven.org/maven2/org/hibernate/hibernate-c3p0/

Cheers, Petar
