Because of a strong and reasonable request from the IBM JVM team, the JSR 292
class file format for CONSTANT_InvokeDynamic is changing one more time. The
current format looks like this:
struct { u1 tag = 18, u2 bsm: MethodHandle, u2 nt: NameAndType, u2
argc, u2 argv[argc] }
The new format will look like this:
struct { u1 tag = 18, u2 bsm_spec: MethodHandle, u2 nt: NameAndType }
The bsm_spec will be an index into an explicit side-table in the class file,
containing an array of the same information as before (MethodHandle, argc,
argv[argc]). The side-table will be a new attribute named "BootstrapMethods".
This format change will make the class file format a easier to parse by some
JVMs (such as J9).
I will be putting out a review request soon for this.
