multiple entry points would also, FWIW, enable OSR. How to invoke a method with a specific entry point? Via Indy, with an extra argument? The handler table that would go away if exception handling was conveniently pushed to a helper object would make a proud reappearance in the form of a valid entry point table. We don't want arbitrary jumps into the middle of things. :-) Best, Michael -- <http://www.oracle.com/> Dr. Michael Haupt | Principal Member of Technical Staff Phone: +49 331 200 7277 | Fax: +49 331 200 7561 Oracle Java Platform Group | LangTools Team | Nashorn Oracle Deutschland B.V. & Co.
