Guillaume Nodet commented on SM-1329:
-------------------------------------
Googling a bit, it seems like the TCCL has no effect on the ObjectInputStream.
I think the way to go is to override it in the JdbcStore to use someting like:
{code}
public class CustomObjectInputStream extends ObjectInputStream {
private ClassLoader classLoader;
public CustomObjectInputStream(InputStream in, ClassLoader classLoader)
throws IOException {
super(in);
this.classLoader = classLoader;
}
protected Class<?> resolveClass(ObjectStreamClass desc) throws
ClassNotFoundException {
return Class.forName(desc.getName(), false, classLoader);
}
}
{code}
as explained at
http://forum.java.sun.com/thread.jspa?threadID=5163767&tstart=300.
I think using this class in the JdbcStore and passing the TCCL as a parameter
may give a good result. We may also need to set the TCCL at the beginning of
the onTimeout method.
