Re: [equinox-dev] Is this a bug?

[Danail Nachev <d.nachev@xxxxxxxxxx>]

If bundles are installed by reference (via reference: URL) Equinox
doesn't guarantee anything to bundles which you replace, while they are
still running. Although OSGi is considered dynamic, such scenarios are
not supported. AFAIK, p2 and old Eclipse Update installs all bundles by
reference.

Such scenarios can be supported if the bundle was copied to the Equinox
storage and not referenced. Bundles which are installed through
Bundle.installBundle(String, InputStream) and
Bundle.installBundle(String) are copied (unless the URL passed to the
installBundle(String) is reference: URL) are copied to the storage.

Does this answer your question?
