 and currently under the supervision of Laurie Hendren and Clark Verbrugge. The name of the group originates from the idea that the original goal was to develop research tools for the programming language Java

Java (programming language)

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

Java

Java is an island of Indonesia. With a population of 135 million , it is the world's most populous island, and one of the most densely populated regions in the world. It is home to 60% of Indonesia's population. The Indonesian capital city, Jakarta, is in west Java...

 also being an island, the group was named after Sable Island

 and AspectJ

AspectJ

AspectJ is an aspect-oriented extension created at PARC for the Java programming language. It is available in Eclipse Foundation open-source projects, both stand-alone and integrated into Eclipse. AspectJ has become the widely-used de-facto standard for AOP by emphasizing simplicity and usability...

 as well as means for the efficient execution of multithreaded programs, e.g. by the form of speculative multithreading

Speculative multithreading

Speculative multithreading , also known as thread level speculation , is a dynamic parallelization technique that depends on out-of-order execution to achieve speedup on multiprocessor CPUs. It is a kind of speculative execution that occurs at the thread level as opposed to the instruction level....

Transaction processing

In computer science, transaction processing is information processing that is divided into individual, indivisible operations, called transactions. Each transaction must succeed or fail as a complete unit; it cannot remain in an intermediate state...

. Premier research tools having been developed over the past years comprise Soot

Soot (computer science)

Soot is a language manipulation and optimization framework consisting of intermediate languages for the Java programming language. It has been developed by the Sable Research Group at McGill University known for its SableVM, a Java virtual machine and the AspectBench Compiler, an open research...
