==Overview==

The core engine is an [[Interpreter (computing)|interpreter]] which used ground-breaking techniques to deliver performance that can approach that of a "naive" [[just-in-time compilation|just-in-time (JIT) compiler]], while retaining the [[software engineering]] advantages of interpreters: [[Porting|portability]], [[maintainability]] and [[simplicity]].<ref>Gagnon, Etienne M., and Laurie J.

SableVM is the first [[open-source software|open-source]] virtual machine for Java to include the support for [[JVMDI]] (Java Virtual Machine Debugging Interface) and [[JDWP]] (Java Debug Wire Protocol).{{Citation needed|date=August 2008}} These standard Java debugging interfaces are used for example by [[Eclipse (software)|Eclipse]] to provide a rich and user-friendly Java development environment.
