`DeadLabelsOption` is a preview API of the Java platform.
Programs can only use `DeadLabelsOption` when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Option describing whether or not to filter unresolved labels. Default is `FAIL_ON_DEAD_LABELS` to throw IllegalStateException when any `ExceptionCatch`PREVIEW, `LocalVariableInfo`PREVIEW, `LocalVariableTypeInfo`PREVIEW, or `CharacterRangeInfo`PREVIEW reference to unresolved `Label`PREVIEW during bytecode serialization. Setting this option to `DROP_DEAD_LABELS` filters the above elements instead.
