Legacy artifact path not properly stored when entered from Archiva UI

For one of the module in our project (which violates artifact conventions) we need to add legacy artifact path. I have tried to add this from archiva admin screen. Please find the attached screen shot for this.

Once it is entered, it come to summary screen. In the summary screen value for the 3rd part is null (i.e) In my example

part[0] -> gp
part[1] -> sr-gp-test
part[2] -> null ---> 3rd part, which is incorrect. I have entered Version for this artifact.
part[3] -> 1.0.2 ---> whatever we entered in Version is misplaced in Classifier.

I have also attached 3rd screen shot when I try to browse this artifact. I went through LegacyArtifactPath.java where these split ups are actually occurring with respect to legacy artifact path.
