Q - anyone else seen a Java LinkageError launching Felix from within
an Applet
Before I go delving deep in the code, I wonder if anyone else has seen a
linkage error like that below when trying to launch a Felix framework
within an Applet
All my JARs are signed, and I've proven that I have access to local
machine resources such as System properties, local folders etc.
Cheers

Thanks - just trying this now in fact, al;so with the FELX-38 mod of
disabling custom URL handlers.
I'm optimistic that it will work ;)

Rob,
I've seen this issue with older versions of Felix and at one point of
time resolved it together with Rick. Is it possible that you use an
old version/revision of Felix? If so, try the 1.0.0 release with
should have fixed it.
In case you still see this problem on 1.0.0 could you maybe try to
provide me with a reproducible example?
regards,
Karl
