Challenges and Scopes of Escape Analysis – A Review on Java Byte Code Optimization

Java is a very promising language, which makes use of JVM for platform independency. Java compiler converts program into byte code which is further executed. There is scope for the optimization in the byte code produced by the compiler. For the static optimization in java one can work on the byte code or different intermediate code of java. The Escape Analysis is a static optimization analysis, which gives the scope for the unnecessary synchronization removal and place objects into the stack instead of heap. This paper describes the scope and challenges of byte code optimization (static analysis) in java especially using Escape Analysis and different supporting analysis.
