[news.eclipse.technology.equinox] Re: Members variables in OSGi Services

[Neil Bartlett <njbartlett@xxxxxxxxx>]

Leo,

Yes indeed. OSGi is an implicitly multi-threaded environment, and not 
just on the server side.

In my book I have devoted a whole chapter to concurrency issues with 
OSGi. It is freely downloadable as a PDF (link to follow) so please take 
a look and come back if you have further questions.

Regards,
Neil
