In the wee hours of this morning, the JVM has for the first time processed a full bootstrap cycle for
invokedynamic instructions, linking the constant pool entries, creating the reified call site object, finding and calling the per-class bootstrap method, linking the reified call site to a method handle, and then calling the linked call site 999 more times through the method handle, at full speed. The method names mentioned by the caller and the callee were different, though the signatures were the same. The linkage was done by random, hand-written Java code inside the bootstrap methdod.
The example code is included in the Email, and also posted (as a truly rebarbative test in a NetBeans project) with the patches. As for the JVM code, it only works on x86/32; the next step is to move the assembler code into the right files, and finish the support for x86/64 and SPARC.
Happy International Invokedynamic Day!
(And by a curious anagrammatic permutation of letters, it could also be International Davinci-Monkey Day. My co-workers, who watched me pounding on my keyboard all summer, claim to see some significance in this.)
