Problem determing proper geometry type with ArcSDE 9.x

In ArcSDE 9.x, the constants in "SeLayer" seem to have changed. This can cause ArcSDEAdapter.getGeometryType() to return an incorrect geometry.

it seems that there are two ways to determine a layer's geometry type:

1) Check its type against the TYPE_* constants, and
2) If that fails, check the type against the various SE_*_TYPE_MASK constants

The problem in this instance is that the SeLayer's geometry type is "2", which corresponds to both TYPE_LINE and SE_POINT_TYPE_MASK. The layer's true geometry is Point, but since it matches against TYPE_LINE in case 1, the wrong geometry type is returned.

With my limited understanding of ArcSDE and the java API it uses, I propose a method to hopefully fix this:
1) Check if the major version of the instance is 9 or higher. If it isn't, proceed exactly as before.
2) If the major version is 9 or higher, do not perform case 1 above. (ie do not check the type value against the TYPE_* constants)

Attached is a patch that makes these adjustments to ArcSDEAdapter on 2.2.x.
