Nikolai,
See if the following modifications are what you're looking for:
.....
t.getRotationScale(rotationScale);
// begin mods:
double tscale = t.getScale();
rotationScale.mul( 1.0 / tscale );
// end mods:
.....
Your test results should now be identical.
AxisAngle4d.set( Matrix3d ) probably needs a pure rotation matrix.
Specifically, can it handle embedded nonuniform scale factors ? May be Chien
can verify this.
