Doubt about task 2480

[Gabriel Ferreira <ga...@gmail.com>]

Hey guys, I'm working in this task
https://issues.apache.org/jira/browse/TOMEE-2480
http://tomee.apache.org/tomee-8.0/examples/simple-rest.html

I dont understant what is the relationship between:
"Here we see a bean that uses the Bean-Managed Concurrency option as well
as the @Startup annotation which causes the bean to be instantiated by the
container when the application starts. Singleton beans with
@ConcurrencyManagement(BEAN) are responsible for their own thread-safety.
The bean shown is a simple properties "registry" and provides a place where
options could be set and retrieved by all beans in the application."

and the REST example, someone can help me?

thanks

Hi Gabriel!

This looks like an copy/paste issue.  That text is clearly taken from this example where those annotations are used and explained:

 - http://tomee.apache.org/tomee-8.0/examples/simple-singleton.html

I suspect it's a simple matter of the example having been created by copying the simple-singleton example as a base and only partially updating the readme:

 - https://github.com/apache/tomee/commit/5d0289a6d26d8ccbcc5f2c687c07a9fe03a3ceaf#diff-afa14df214dc2363cc66e7aa4bf48e1e

If you wanted to completely rewrite it or update it in any way, I say go ahead!
