Given that helper.loadClass uses the context class loader,
Should you also simply use
ServiceLoader<InitialContextFactory> loader =
at lines 680-681 ?
Also it might be good to log an RFE against the ServiceLoader, so
that you could look for a service implementation of a specific
concrete class without having to instantiate all the other
service implementations encountered along the way.
Streams should provide a nice infrastructure for such an API.
It would certainly be more robust than looping over
ServiceLoader.iterator().next() - which is unfortunately the only
option available to you at the moment.
This seems a bit fragile to me - unless it's guaranteed that
the various InitialContextFactory have no static initializer
that might throw exceptions (such as SecurityException) - and
that their default constructor does nothing (so that instantiating
e.g. com.sun.jndi.cosnaming.CNCtxFactory when you're actually
looking for com.sun.jndi.ldap.LdapCtxFactory has no side effect
- which fortunately seems to be the case).
Also - it would be good to clarify the specification of
public static Context getInitialContext(Hashtable<?,?> env)
It was not clear to me that you would loop over all the
services found by the ServiceLoader until you'd find one
whose concrete class matched the name pointed to by
