RequestHandler ReadOnlyContext NullPointerException initialization

[GoogleCodeExporter]

Hi,

we are facing a NullPointerException with the first request proceeded.

As you can see from the logs files, the context in ReloadCacheRequestHandler 
class is null : 
{{{ 
java.lang.NullPointerException
    at ro.isdc.wro.http.handler.ReloadCacheRequestHandler.isEnabled(ReloadCacheRequestHandler.java:57)
}}}

We are using the simple DefaultRequestHandlerFactory.
This problem can also be duplicated with another RequestHandler like 
ReloadModelRequestHandler and we were able to reproduce in debug mode or not.

Finally, to avoid this problem we encapsulated the instatiation like this :
{{{
public class MyRequestHandlerFactory implements RequestHandlerFactory {

    private Collection<RequestHandler> handlers = Collections.emptyList();

    @Override
    public Collection<RequestHandler> create() {
        if (CollectionUtils.isEmpty(handlers)) {
            handlers = new DefaultRequestHandlerFactory().create();
        }
        return handlers;
    }
}
}}}

Could you try with latest snapshot version (build from branch 1.7.x)? I think 
one of the fixed issues is similar to this one.
