The following program returns different results on Java 8 and Java 9:

public class zz
{
    public static void main( String... args ) throws Exception
    {
        System.out.println( java.lang.StrictMath.toRadians( 2.225E-307 ) );
    }
}

On 1.8.0-b132 the result is 3.88335758568738E-309

On 1.9.0-ea-b33 the result is 3.883357585687384E-309

We are seeing this discrepancy in the regression tests for Java DB on Solaris_sparc_jdk9. I am seeing this on Mac OSX as well. See http://sthjavadb01.se.oracle.com/javadb-testing/request_5597089/
