ArrayIndexOutOfBoundsException when adding a new API in wso2am - wso2

Question

I downloaded wso2am-1.9.0.zip to my MacBook and expanded it. I did not change any of the config or anything else. I started it up with bin/wso2server.sh, as documented. It seemed to start up successfully. I was able to login to the API Publisher with admin/admin, as documented. When I tried to add a simple new API (just one endpoint) I got the following stacktrace:

This issue occurs when you give context as /{version}. This issue [1] is already identified and in open state and will be fixed in up coming releases. As a work around you can provide some other value as well to your context and create the api. E.g., test/{version} or /{version}/test or test/{version}/somestring
