Issue #49: whether empty input is considered legal or not. If set to true, empty content is allowed and will be read as Java 'null': if false, an IOException will be thrown. 

NOTE: in case of JAX-RS 2.0, specific exception will be javax.ws.rs.core.NoContentException;
but this is not defined in JAX-RS 1.x.

Feature that may be enabled to force dynamic lookup of ObjectMapper
via JAX-RS Provider interface, regardless of whether MapperConfigurator has explicitly configured mapper or not; if disabled, static configuration will take precedence. Note that if this feature is enabled, it typically makes sense to also disable CACHE_ENDPOINT_READERS and CACHE_ENDPOINT_WRITERS since caching would prevent lookups. 

Feature is disabled by default.
