Whiley 0.4.9

Whiley is a programming language with refinement types, extended static checking and an indentation-based syntax. It compiles to Java bytecode and runs per JAR-runtime on any JVM, which in turn allows to reuse existing Java libraries. The SDK includes a compiler (wyjc), documentation, a plugin framework, disassembler, and an Eclipse plugin.
