Re: ATCT vs. PicoThreads
Well, PicoThreads and Brakes (
use similar approach to capture/restore state of computation in the JVM.
It is based on bytecode instrumentation when injected code fragments access
and modify JVM stack.
Unfortunately, in many cases such operations are not safe from the bytecode
verifier point of view
and in newest JVMs it rejects classes instrumented this way.
ATCT uses completely different mechanism based on secondary bytecode
interpreter (written in Java)
that executes methods marked as "Continuations Enabled".
Actually ATCT uses serializable thread semantics instead of continuations as
well as Brakes do.
