Thread Safety in Singletons and Statics

[Bijan Vakili, módosítva 9 év-val korábban]

Hi would you consider below thread-safe?
com.liferay.portlet.PortletContextFactory
Seems vulnerable to write-over-write
This is template of thread safety issue; same pattern can be found in more places; are we handling this issue somehow?

It's like a servlet context, you get one (some) created at portlet startup. The context doesn't change during runtime. Sure it's not decorated with the synchronized keyword, but it should be just fine.

Thanks David; agreed, it is a moot point. I reviewed portal-service and looks fine. Thanks for your prompt and insightful reply.
