Folks (well, primarily John I think),
I'm trying to write a testcase for an invokedynamic call that
specifies "dyn:getprop:helloText" as the method name. So far, I've
tried the following (all using ASM to generate bytecode as I don't
know what if any is the javac-recognized syntax for these):
1. specify the name verbatim as "dyn:getprop:helloText" in the
argument to invokedynamic. Gives me the following exception when I
call CallSite.nameComponents():
[junit] java.lang.Character
[junit] java.lang.ArrayStoreException: java.lang.Character

sun.dyn.util.BytecodeName.parseBytecodeName(BytecodeName.java:324)

23)

10)
2. specify the name mangled as either "\=dyn\!getprop\!helloText" or
"dyn\!getprop\!helloText". In neither case will CallSite.name()
demangle it, nor will CallSite.nameComponents() either demangle or
tokenize it - I get back a single-element array with the full mangled
name.
Am I doing something wrong?
Attila.
