The errors reported are:

/localhome/git/jdk-BAR/closed/test/jdk/java/awt/sizecalc/SafeAllocationTest/libSafeAllocationTest.c:75:13: error: format specifies type 'unsigned long long' but the argument has type 'int64_t' (aka 'long') [-Werror,-Wformat]
            m, n, allocated);
            ^

            m, n, allocated);


There seem to be some underlying type confusion. A (probably better) alternative to hiding the warning is to actually fix the problem. I'll leave that question up for the client team to decide if they want to address this.
