The _org.hibernate.boot.registry.classloading.internal.ClassLoaderServiceImpl_ stores the thread context classloader during the startup. Since this ClassLoader is only available during the bootstrap, all further call to it will cause a warning in the logs, having the following stack:

This is done by the following piece of code in the class constructor (line 83):
{code:java}
// then the TCCL, if one...
final ClassLoader tccl = locateTCCL();
if ( tccl != null ) {
orderedClassLoaderSet.add( tccl );
}
{code}
Actually, this has no functional impact since the needed classes will always be found in the provided ClassLoader which is given by the _EntityManagerFactoryBuilderImpl_ (line 360) because it's the PersistenceUnit's one and will always be available.
However, the adding of the TCCL should be configurable by a property and/or be platform-configured by default (for Glassfish, _SunOneJtaPlatform_).
I attached a patch as proposal for a fix, which adds the property _hibernate.classloader.tccl_lookup_ which can handle the values _never_,_before_,_after_, although I'm not sure it is relevant to handle the _before_ and _after_ behaviours... But I think it's interesting to have them since the thread context ClassLoader could change during the runtime.
Any feedback would be appreciated.
Thanks in advance.
PS. This issue replaces HHH-11243
