Code polish: replace classic for-loop with enhanced

[govi20]

ApplicationContext has classic-for loops, these for loops can be replaced with enhanced for-loop to improve code readability.

The patch is smaller is you don't replace listener with servletContextAttributeListener everywhere. Any reason to re-name this local variable reference?

[govi20]

Yes. for-loop's temp variable and ServletContextAttributeListener's old var name were clashing. I don't think using tempListener in a for-loop declaration would be a good idea.

for (Object listener : listeners) listener fits here semantically hence I have renamed other variables

for (Object obj : listeners) {... results in a cleaner patch. I've applied that version to master and will back-port shortly. I've also applied some other clean-up and will back-port that too.

Cool Thanks!
