I removed ACCEPT_INCOMPLETE from MODE_PERMISSIVE. and add a new MODE_PERMISSIVE_NEW that enabling all the flag. and I think that this change need some extra doc. /**
* smart mode, fastest parsing mode. accept lots of non standard json syntax ACCEPT_INCOMPLETE
* feature is not enabled. in this mode, for backward compatibility
*
* @since 1.0.6
*/
public static final int MODE_PERMISSIVE = -1 & ~ACICEPT_INCOMPLETE;
/*
