JBPM 5.0 Released With BPMN 2.0 Spec Support

This release features a core engine that supports the native execution of business processes, in keeping with the BPMN 2.0 spec, a process repository for managing process definitions, and Eclipse tooling. There is also web-based tooling for business users, such as web-based editing of business processes and human task lists.

Google Launch Contracts for Java

Google have launched a new open source tool, Contracts for Java, which enables users to annotate their code with contracts in the form of preconditions, postconditions and invariants. Enabled via a JVM argument, these contract annotations are checked at runtime. Contracts can also be used to help turn interface documentation into code.

Here is an example of a Java class annotated with contracts:

interface Time {

    "result >= 0",
    "result <= 23"
  int getHour();

    "h >= 0",
    "h <= 23"
  @Ensures("getHour() == h")
  void setHour(int h);



The project is available from Google Code.
