java.awt.Rectangle2D.Double


Attached are some tests for the Rectangle2D.Double class.  All checks
pass for me using JamVM 1.1.4 and JDK 1.4:

dgilbert@linux42:~/workspace/mauve> jamvm -cp .
gnu.testlet.SimpleTestHarness -file Rectangle2DDoubleTests.txt -debug
0 of 67 tests failed
dgilbert@linux42:~/workspace/mauve> java -cp .
gnu.testlet.SimpleTestHarness -file Rectangle2DDoubleTests.txt -debug
0 of 67 tests failed

Regards,
