resteasy-guice's RequestScopeModule has a recursive toString implementation

resteasy-guice's RequestScopeModule has RequestScoped scope binding, which has a toString implementation which implicitly calls itself through String.format. This will result in java.lang.StackOverflowError.

The offending line is at RequestScopeModule.java line 52:

@Override
public String toString() {
    return String.format("%s[%s]", creator, this);
}
