I'm building with --disable-warnings-as-errors but the build still fails:

Is there a maximum number of warnings allowed before it's considered an error? Could this be coming from (s)javac? (The warnings are Java related).

I was told about -Xmaxwarns for javac and I bumped it to 1000 but it didn't help much:

1 error
138 warnings
...

I finally spotted this in the log:

error: warnings found and -Werror specified

From the make-support/failure-log I see -Werror in the javac command line. Obviously it isn't adhering to --disable-warnings-as-errors! :(
We've stumbled across this before. It's obviously not what one would expect. Could you open a bug for it?
