Summary: Bean's methods invoked in thread with invalid context classloader

Description Jan Stola 2006-02-16 11:08:54 UTC
The constructor of the bean and its getters and setters are invoked
in the event-dispatch thread with the context classloader set to NetBeans
system classloader. This causes problems to beans that try to utilize
thread's context classloader (like DriverManager invoked through

We cannot set the context classloader for all invocations (e.g. painting
methods), but we should consider temporary setting of the context classloader
when invoking constructor and setters.

Noone reported issue caused by this imperfection. So, it doesn't seem to cause problems in real-world forms => changing 
to enhancement.

Bug 231916 would need this context classloader - to be able to load Hibernate copies for particular user projects, which seemed to work (kind of) when experimenting with it, but this example is not a suitable case either as Hibernate is too big to be fooled this way (not designed for such use), easy to fail on something else.

But the idea of setting the context classloader to the project class loader when instantiating beans (or executing any code in FormLAF block) seems generally reasonable.
