Thanks I get the same results as you now:
FAIL: gnu.testlet.java.awt.geom.AffineTransform.createTransformedShape (number 10)
FAIL: gnu.testlet.java.awt.geom.AffineTransform.inverseTransform (number 4)
FAIL: gnu.testlet.java.awt.geom.AffineTransform.inverseTransform (number 6)
FAIL: gnu.testlet.java.awt.geom.AffineTransform.inverseTransform (number 8)

FAIL: gnu.testlet.java.awt.geom.AffineTransform.inverseTransform (number 14)
6 of 257 tests failed

No, the way you do it is correct.
Someone investigated it for some other implementation and decided that
the current behavior is the expected one. Even though I don't completely
agree with the reasoning it doesn't make sense to deliberately do
something different.

Checked in all the new tests as follows:
