In this case, the compiler advises recompiling with <tt>-Xlint:unchecked</tt> to see what the problem is. As we found a couple of years ago when we tried to stomp on some of this, it can be very hard to untangle in some cases so this is not something we want to have turned on unless and until we are clear of the issue already.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">However, it's hard without some support from Maven to see what the actual issue is. I propose adding a new "lint" profile to the parent project analogous to the "release" profile, adding this:</p>
