Re: [equinox-dev] Possible problem with classloaders
|
Take a look at Section 11 of the OSGi Core Specification ("URL Handlers
Service Specification"). As it states in the introduction:
"This specification is necessary because the standard Java mechanisms for
extending the URL class with new schemes and different content types is
not compatible with the dynamic aspects of an OSGi Service Platform. The
registration of a new scheme or content type is a one time only action in
Java, and once registered, a scheme or content type can never be revoked.
This singleton approach to registration makes the provided mechanism
impossible to use by different, independent bundles. Therefore, it is
necessary for OSGi Framework implementations to hide this mechanism and
provide an alternative mechanism that can be used."

advice.
