Remove javac options that confuse javadoc

[raboof]

The javadoc tool returned an error (and failed the build) for me because of the
-Xlint:unchecked option which is passed to javadoc but not
recognized there.

Which command failed for you? AFAICS unidoc does not generate Javadoc in Alpakka.

sbt package is fine, but sbt publishLocal gives the error for me

This is interesting. Since the spring-web alpakka module has only Java code, the spring-web/compile:doc task starts javadoc (in contrast this task for all other projects starts scaladoc).

The proper fix would be to scope the javacOptions to compile task, so it is not picked up by the doc task:

diff --git a/project/Common.scala b/project/Common.scala
index bcb767c..8e74141 100644

Nice. Validation issue was #527
