Dan McNulty 48b4502d1d Move EmptyHttpHeaders.INSTANCE initialization to inner class. ... Motivation: If the HttpUtil class is initialized before HttpHeaders or EmptyHttpHeaders, EmptyHttpHeaders.INSTANCE will be null. This can lead to NPEs in code that relies on this field being non-null. One example is the LastHttpContent.EMPTY_LAST_CONTENT.trailingHeaders method. Modifications: - Move HttpUtil.EMPTY_HEADERS to a private static final inner class of EmptyHttpHeaders called InstanceInitializer. - Add tests, that when run in isolation, validate the fix for the issue. Result: Any initialization order of HttpUtil, EmptyHttpHeaders or HttpHeaders will result in EmptyHttpHeaders.INSTANCE being initialized correctly.		2017-11-17 16:31:09 +01:00
