Normally, a VM defines the semantics of it's programming language. In case of Java, the corresponding instruction set represents a multi-threaded stack machine, where values are kept on the heap, or ...

In computer science, an instruction set architecture (ISA) is an abstract model of a computer. It’s also referred to as architecture or computer architecture. Moreover, a central processing unit (CPU) ...

Reading compiled Java bytecode can be tedious, even for experienced Java developers. Why do we need to know about such low-level stuff in the first place? Here is a simple scenario that happened to me ...

Abstract: Techniques are presented for reducing the performance overhead of switch instructions in a multicore hardware-accelerated Java virtual machine. The bytecode instruction set is extended with ...

Abstract: Pattern-based Java bytecode compression techniques rely on the identification of identical instruction sequences that occur more than once. Each occurrence of such a sequence is substituted ...

Q: If I encrypt my .class files and use a custom classloader to load and decrypt them on the fly, will this prevent decompilation? A: The problem of preventing Java byte-code decompilation is almost ...
