             Summary: Wasted work in InternalQueueConfiguration.checkIsValid()
                 Key: SLING-2925
                 URL: https://issues.apache.org/jira/browse/SLING-2925
             Project: Sling
          Issue Type: Bug
          Components: Scripting
         Environment: any
            Reporter: Adrian Nistor


The problem appears in version 6 and in revision 1495454.  I attached
a one-line patch that fixes it.

In method "InternalQueueConfiguration.checkIsValid", the loop over
"matchers" should break immediately after "hasMatchers" is set to
"true".  All the iterations after "hasMatchers" is set to "true" do
not perform any useful work, at best they just set "hasMatchers" again
to "true".

Method "isLive" in class "ResourceResolverContext" has a similar loop
(over "dynamicProviders"), and this loop breaks immediately after
"result" is set to "false", just like in the proposed patch.  Other
methods (e.g., "FactoryPreconditions.checkPreconditions",
"JspUtil.checkAttributes", "EclipseJavaCompiler.compile",
"SecondPassVisitor.appendPageDirective") also have similar loops with
similar breaks, just like in the proposed patch.
