[Insight-users] Odd java wrappers behavior

Hi Brian,
Thanks for your detailed report.
Judging from the Java thread that you posted, the error
seems to be triggered when GetParameters() is invoked
in the transform.
itkCenteredRigid2DTransform_GetParameters
That leads to suspect that the problem is actually related
to the lack of initialization in one of the transforms.
The fact that it shows up when you first instantiate
these other ITK objects seems to be coincidental...
Could you please give us some details on how you are
initializing the transforms before you attempt to write
out their parameters ?
Thanks
Luis
