openid4java ConsumerManager request/thread safe?

Question

I am using openid4java in servlets. I have two servlets - one which performs first step (redirects user to login/accept application access) and second, which processes resulting information

In the documentation, there is written, that org.openid4java.consumer.ConsumerManager class must be the same instance in both steps. Can I create singleton for that? Is it thread and request safe?

Thanks for your replies!

Answer 1

In the consumer servlet from official openid4java sample it seems that ConsumerManager is thread safe - they use single ConsumerManager instance for all sessions. I use it this way too and have not noticed any strange behaviour yet. But a javadoc statement about thread-safety from the developers would be great...
