NoSuchMethodError when adding git creds for CodeStar project

[bellkev]

I got this error when attempting to add the https creds for a CodeCommit repo when going through the wizard to add a CodeStar project. Full error log here: https://gist.github.com/bellkev/89d214adba5cd40eff5e5bbd53cc1bd9

Appears to be coming from here: https://github.com/aws/aws-toolkit-eclipse/blob/master/bundles/com.amazonaws.eclipse.core/src/com/amazonaws/eclipse/core/egit/ui/SourceBranchPage.java#L200

Also, it seemed to be benign, and I could still import the project.
