Key: HHH-2281

Project: Hibernate3
Type: Bug
Versions: 3.2.1
Environment: Hibernate checked out from trunk; revision 10717
Reporter: Sergey Polzunov
Calling Session.connection() always generates an exception. Here is the stacktrace I get
from the attached test case:
Exception in thread "main" java.lang.IllegalArgumentException: interface
org.hibernate.jdbc.ConnectionWrapper is not visible from class loader
at java.lang.reflect.Proxy.getProxyClass(Proxy.java:353)
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:581)
at
org.hibernate.jdbc.BorrowedConnectionProxy.generateProxy(BorrowedConnectionProxy.java:56)

at org.hibernate.jdbc.JDBCContext.borrowConnection(JDBCContext.java:111)
at org.hibernate.impl.SessionImpl.connection(SessionImpl.java:359)
at TestSession.main(TestSession.java:16)
Changing the Connection.class.getClassLoader() to
BorrowedConnectionProxy.class.getClassLoader() on line 57 in the generateProxy() method
solves the problem. I am not very familiar with class loaders so I don't know if this
is likeley to cause other problems elsewhere. Removing the ConnectionWrapper.class from
the PROXY_INTERFACES array in the org.hibernate.jdbc.BorrowedConnectionProxy also solves
the problem, but I guess it was added for a reason.

Fabio Da Soghe commented on HHH-2281:
-------------------------------------
Maybe it can help another confirm: I get this problem developing an Eclipse RCP plugin
(RCP 3.2, HIbernate 3.2.1.ga).
With Eclipse RCP there is a notable issue regarding classloading and Hibernate (as you
surely know), resolved by the Buddy Loading mechanism.
But the error described here seems different and I wasn't able to resolve it with any
Buddy Loading solution (I did several tries). Indeed I was confident I didn't need the
Buddy Loading, since I have only one RCP plugin with all classes into it (Hibernate
library and user client classes).
I got my application running without this exception by returning to Hibernate 3.2.0. No
need of Buddy Loading neither any other workaround: the plain plugin configuration works
well.
If needed, I can supply other details (source code, plugin and runtime configuration,
etc).
Best Regards,
Fabio

Rodrigo Cesar Gevaerd de Faria commented on HHH-2281:
-----------------------------------------------------
I got exactly the same stack trace in the following enviroment with Hibernate 3.2.3ga:
- Tomcat with webapp-A and webapp-B.
- webapp-A contains hibernate libraries, webapp-B don't.
- webapp-A dispatchs to a jsp in webapp-B, including in the request an attribute that
implements an interface available in the shared class loader. Webapp-B calls that
interface instance webapp-A made available. This operation in webapp-A calls
session.connect(), and the error occurs.
Setting the current thread context class loader to null before calling the
Session.connection(), and putting it back later, served as a workaround for me.

Steve Ebersole commented on HHH-2281:
-------------------------------------
The "fix" is the deprecation of Session.connection() and scheduled removal in
4.0...
It will be replaced with a way to pass in to Hibernate some "work" you want to
have access to the connection. This still gives users access to the connection, but does
not mess with Connection handling inside Hibernate.

---------------------------------------
FYI, Juergen responded to my issue in the Spring JIRA with a couple possible workarounds.
He also suggested a simple Hibernate fix that maybe can make it into a 3.2.x release?
"Hibernate shouldn' be using the thread context ClassLoader there...
BorrowedConnectionProxy.class.getClassLoader() would be correct, completely ignoring the
thread context."

---------------------------------------
For folks seeing this issue via Spring JMX, I successfully tested one of Juergen's
suggested workarounds which was to set MBeanExporter's
"exposeManagedResourceClassLoader" property to "true"

Key: HHH-2281

Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.1
Environment: Hibernate checked out from trunk; revision 10717
Reporter: Sergey Polzunov
Calling Session.connection() always generates an exception. Here is the stacktrace I get
from the attached test case:
Exception in thread "main" java.lang.IllegalArgumentException: interface
org.hibernate.jdbc.ConnectionWrapper is not visible from class loader
at java.lang.reflect.Proxy.getProxyClass(Proxy.java:353)
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:581)
at
org.hibernate.jdbc.BorrowedConnectionProxy.generateProxy(BorrowedConnectionProxy.java:56)
at org.hibernate.jdbc.ConnectionManager.borrowConnection(ConnectionManager.java:163)
at org.hibernate.jdbc.JDBCContext.borrowConnection(JDBCContext.java:111)
at org.hibernate.impl.SessionImpl.connection(SessionImpl.java:359)
at TestSession.main(TestSession.java:16)
Changing the Connection.class.getClassLoader() to
BorrowedConnectionProxy.class.getClassLoader() on line 57 in the generateProxy() method
solves the problem. I am not very familiar with class loaders so I don't know if this
is likeley to cause other problems elsewhere. Removing the ConnectionWrapper.class from
the PROXY_INTERFACES array in the org.hibernate.jdbc.BorrowedConnectionProxy also solves
the problem, but I guess it was added for a reason.

tahura chaudhry commented on HHH-2281:
--------------------------------------
I'm using Spring 2.5.3 and Hibernate 3.2.1ga.jar
I'm using Spring JMX in my application and am running into the same issue. I tried
the workaround of setting "exposeManagedResourceClassLoader" property to
"true" (which is the default value in 2.5.3) but that did not seem to help.
I'm wondering if there is anything else I need to do in order to get the workaround
working.
thanks,
