- Java provides only a restricted form of polymorphic methods,
namely single-receiver dispatch. In common programming
situations, developers must work around this limitation. We
describe how to extend the Java Virtual Machine to support
multi-method dispatch and examine the complications that Java
imposes on multi-method dispatch in practice. Our technique
avoids changes to the Java programming language itself, main-
tains source-code and library compatibility, and isolates the
performance penalty and semantic changes of multi-method dispatch to the program sections which use it. We have micro-benchmark and application-level performance results for a dynamic Most Specific Applicable (MSA) dispatcher, a framework-based Single Receiver Projections (SRP) dispatcher, and a tuned SRP dispatcher.
