static final String STRING_KEY_PATTERN = "[a-z0-9_-]{1,120}";

I came across an exception where my key length exceeded 64 characters, so I was browsing through the repo to figure out a reason for this cap on key length. It seems after the key length was increased, the newer jar never got deployed to maven/bintray.
