Time to start looking for alternatives to Wercker
Going by Oracle's past behaviour with software acquisitions, Wercker's stuff is going to get completely fucked.
MySQL: fucked. Use MariaDB instead.
Open Office: fucked. Use Libre Office instead.
Solaris: fucked. Use Linux instead.
Java: well on its way to being fucked, although I never thought that much of it anyway. Use anything but Java instead.
