Java NPE when importing a project

I have a test IDM 4.8 environment running on RHEL 7.  When I try to import the project into Designer, it throws a Java null pointer exception and won't import anything except the vault and schema -- no drivers. 

I've tried this from three different machines running two different versions of Designer (4.7 and 4.8) with the same result.  Has anyone else seen this?

(editing to add that I am able to import projects from three other IDM environments - two 4.8 and one 4.6.4 -  without this problem)

 

Here is the error:

java.lang.NullPointerException
