it be nice to allow users to set the parent class loader as per their

Equinox allows users to configure the parent [1].
Yes, I agree it might be nice to make this configurable.
What is confusing is that although the parent is automatically set to
"system class loader," it is not used for any kind of delegation.
Instead, Felix delegates to the class loader that loaded Felix framework
classes for any kind of class loading delegation. I am saying this based
on the following code that I see in R4SearchPolicyCore.java:
result = (isClass)
? (Object)
getClass().getClassLoader().loadClass(name)
: (Object)
getClass().getClassLoader().getResource(name);
If this is the only delegation point, then it should not be that
difficult to provide a configuration point to user, should it?
FYI, remember OSGi doesn't follow the classic parent
classloader delegation model, which is why I think the
setting of the parent loader is really only of interest to
code that explicitly uses the ClassLoader.getParent()
method
but it would still be useful to make this configurable
(ie. the setting of the parent loader, not the above
search policy which I believe follows the spec...)
The search policy is delegating to getClass().getClassLoader(). Where
does the spec mandate it to delegate to the class loader that loads the
framework? Can you please send a pointer to the spec?
Thanks,
Sahoo
