NullPointerException in SSHKeyProvider since update to Bamboo 6.4.0

[Daan Kets]

Yesterday, we updated our bamboo to version 6.4.0, and as of then, the SCP task no longer works: it throws the NPE below. As a result, all of our deploy jobs now fail. This happens both with custom and shared credentials.

Error occurred while running Task 'Copy binary to server(3)' of type com.atlassian.bamboo.plugins.bamboo-scp-plugin:scptask.
