RFR 8073853: KeyToolTest.java has too many too long lines

[Weijun Wang]

Hi Sean

Please review the change at

   http://cr.openjdk.java.net/~weijun/8073853/webrev.00

After the change, the output of the following command does not change at 
all.

   javac -g:vars,source KeyToolTest.java

Thanks
Max
