I have two bundles A and B, A optionally requires B. B is installed
using BundleContext#installBundle after A had already been running. The
problem is, I have to restart Eclipse in order A to start see classes
available from B. I tried to "refresh" B as suggested by other posts in
this group. I tried to stop and restart A, refresh A, but nothing
worked. Am I missing something?

It is not because A is marked as "uninstalled" that its classloader has
been successfully garbage collected. If another plugin holds reference
to it A is still around.
To make sure everything works fine, you should try to make A and B as
simple as possible, and ensure that no other plugin depend on A.

Sorry Pascal, but I am not sure I understood what you meant.
My plugin A is slightly modified "Hello, World" template plugin which
tried to reference classes provided by B. I am 100% sure that nothing
requires A. B is a trivial non-UI plugin that has only one jar file and
provides all packages from that jar.
The way I test this:
1. Press "Sample Action" toolbar button, get "class not found error"
2. From OSGI console
2.1 install/refresh B
2.2 tried all combinations of stop/start/refresh A
3. Press "Sample Action" again, same class not found error.
I do not see how I can make it simpler than that :-)

What you are doing did not work out of the box as once A's classloader is
created its dependency graph is set in stone (well it is somewhat
malleable). Refreshing A should have fixed this.
