We fixed this problem with a rather cruel hack, but it works:
In unsqueeze:
...
psf String CGLIB_TOKEN = "CGLIB";
psfs CGLIB_ADDED_SIGNS ="$";
...
public Object unsqueeze(DataSqueezer squeezer, String string)
{
...
String classname = parts[1];
if(classname.indexOf(CGLIB_TOKEN) > 0)
classname = classname.substring(0,
classname.indexOf(CGLIB_ADDED_SIGNS));
...
}
We have modified the squeezer example in the wiki a bit, but you should
be able to get the general idea of it.
Dunno what will happen if we turn of CGLib enhancement in Hibernate
though. Not tested yet :-)
HTH.
