Hi Serge (sorry, I forgot to mention you in my last mail), hi Nick,
Thanks for the tips Nick, I did not thought about putting breakpoints into
Felix to see which bundle refresh what, will try it for sure.
Tim, I personally see the proxy issue with @Transactional as only a
technical/implementation issue: as a user, I really can't see the point
that using:
[code]
private int txGet() {
txControl.required(() -> {
return 42;
}
}
[/code]
is more modularity-friendly than
[code]
@Transactional (propagation=REQUIRED)
private int txGet() {
return 42;
}
[/code]
Finally, I want to personally thank you for your book that has a place of
choice in my library and brought me an unconditional love and interest for
the OSGI technology!
Best regards to all :),
