Accept-Encoding header causes Spring to throw 500 errors

[joeyvmason]

If Content-Type request header is application/json instead of application/json;charset=UTF, then providing Accept-Encoding values other than UTF-8 (e.g. gzip, deflate, sdch) will result in 500 errors when running on AWS Lambda. Have not been able to reproduce this locally, but it happens without fail when run on AWS Lambda.

Full stack trace:
