Recently I observed some some interesting behaviors while trying
to use JRE
defined property called "java.protocol.handler.pkgs" to locate
URLStreamHandler. Yes, I know I should be using OSGi URL handler
service,
but that's a separate discussion. Here are my observations:
1. I don't see any Handler for *bundle* scheme. So, if I disable
urlhandler
service (felix.service.urlhandlers=false in config.properties),
then any URL
with *bundle* scheme can't be used. Should there not be handlers
for all
Felix defined schemes?
I don't think that the bundle protocol handler would be generally
useful. It's only meaningful in the context of a framework and as such
implementation specific as well...
Does Felix not return URL with bundle scheme for any resource found
in a bundle? If yes, how JVM use that URL when urlhandler service is
switched off?
Felix uses the URL constructor that accepts a stream handler and we
pass in our custom handler there. Of course, this means that you
cannot convert the URL to a string and then back to a URL, but there
isn't much we can do about that.
Could Felix not have a Handler like org.apache.felix.bundle.Handler so
that one could add it to the pkg list that JVM searches for custom url
handlers?
Not really, because the handler would have no way of knowing which
framework instance it was associated with.
