Re: [equinox-dev] [Aspects] AOSGi without Eclipse

[Thomas Watson <tjwatson@xxxxxxxxxx>]

In the framework we currently assume
that framework extensions that provide framework hooks are installed as
framework fragments.  The OSGi spec mandates that framework fragments
must be appended to the classpath of the framework's classloader.  The
bootstrap launcher (the old startup.jar) always ensures that the org.eclipse.osgi.jar
is the first thing on the classpath for the framework's classloader.  If
you are not using the bootstrap launcher to launch the framework then you
must set your classpath correctly so that the org.eclipse.osgi.jar is first.

With that said, we could make this easier
by marking the resource provided by the framework as special and ensure
that we process it first.  Perhaps you should open a bug against Equinox->Framework
so we can discuss and consider this.

Thanks.

Tom

The order in which hooks, that are contributed by different bundles, depends
on CLASSPATH rather than any other explicit control (because of the use
of ClassLoader.getResources()). In particular system provided hooks, whose
contribution others may rely on, may not be invoked first. Was this intended?
Is this bad practice on my part? If I don't rely on the default hooks I
will have to parse the manifest myself which seems wrong.
