Oops; "NameAndType" is a mistake. That bit is supposed to summarize the Javadoc I sent earlier. The index is actually a CONSTANT_Fieldref, CONSTANT_Methodref, or CONSTANT_InterfaceMethodref, depending in the ref_kind. It is not a CONSTANT_NameAndType.
Change the summary to:
- u2 NameAndType ref_index
+ u2 ( Fieldref | Methodref | InterfaceMethodref ) ref_index
The javadoc regarding the ldc/MH feature is unchanged.
