-------------------------------------
Emmanuel, I'm working with a J2SE 1.4 included in Bea WebLogic 8.1; the stack trace is
the following:

So, the error occurrs not on line 204:
Constructor constructor = concurrentStatsClass.getConstructor(new
Class[]{SessionFactoryImplementor.class});
It's not a problem of instantiation, it's a linker error.
NoClassDefFoundError when using Hibernate 3.5 with J2SE 1.4 because
of a wrong catch block
------------------------------------------------------------------------------------------
Key: HHH-5329
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5329
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.0-Final
Environment: Hibernate 3.5, Java SE 1.4 or J2EE 1.3
Reporter: Francesco Poli
Assignee: Emmanuel Bernard
Priority: Blocker
Fix For: 3.5.x
In org.hibernate.impl.SessionFactoryImpl is done this check when looking for concurrent
classes during the creation of the SessionFactory:
Statistics concurrentStatistics = null;
try {
Class concurrentStatsClass =
ReflectHelper.classForName("org.hibernate.stat.ConcurrentStatisticsImpl");
Constructor constructor = concurrentStatsClass.getConstructor(new
Class[]{SessionFactoryImplementor.class});
concurrentStatistics = (Statistics) constructor.newInstance(new Object[]{this});
log.trace("JDK 1.5 concurrent classes present");
} catch (Exception noJava5) {
log.trace("JDK 1.5 concurrent classes missing");
}
But what is thrown is a NoClassDefFoundError, which is not an Exception.
As a consequence, the catch block won't work and the error is propagated to the upper
levels of the application.
I suggest to modify the catch arguments to match the correct type of the thrown object.
Thank you.
Bye
Francesco Poli
