Uwe Schindler commented on LUCENE-5551:
---------------------------------------
Sorry, I did not know that {{averages[block]}} or {{f}} in your example was a
float - I was expecting that it is an int, too! This makes it more crazy. We
should be really careful!
This just confirms my problem: The coder had an idea why he casted like that
:-) Redundant casting is not really a warning, it dont hide bugs, it makes it
explicit what was intended, so its just there for clarification. Just because
javac automatically casts something accoring to java standards, it does not
mean we should really take it as it is. I prefer explicit casts around
primitive types!
I would suggest to disable the warning in the eclipse config file in
dev-tools/eclipse!

> The build produces a lot of warnings. LUCENE-5130 aims to fail the build on
> certain warnings, but until we actually eliminate those warnings from the
> code, failing the build is premature.
> This issue is concerned with fixing or suppressing warnings reported by the
> ant build, anything further than that may need one or more separate issues.
