Executing native:javah goal results in "error in opening zip file"

When executing native:javah goal from within Eclipse, I get "error in opening zip file".
When executing the Maven target, "Resolve Workspace artifacts" and "Debug Output" are enabled.
I have attached an example project illustrating the bug.
