Open Source Java Compilers

X10 is a class-based, strongly-typed, garbage-collected, object-oriented language. To support concurrency and distribution, X10 uses the Asynchronous Partitioned Global Address Space programming model (APGAS). This model introduces two key concepts -- places and asynchronous tasks -- and a few mechanisms for coordination. With these, APGAS can express both regular and irregular parallelism, message-passing-style and active-message-style computations, fork-join and bulk-synchronous parallelism. Both its modern, type-safe sequential core and simple programming model for concurrency and distribution contribute to making X10 a high-productivity language in the HPC and Big Data spaces. User productivity is further enhanced by providing tools such as an Eclipse-based IDE (X10DT). Implementations of X10 are available for a wide variety of hardware and software platforms ranging from laptops, to commodity clusters, to supercomputers.

Data Manipulator is a pure Java GUI interface for SQL databases. Not only an administrative tool, but one that allows a user to create forms and reports. Additionally A Java programmer can use code with Forms, reports a stand alone to manipulate the data

Flow4J is a java framework, that enables the user to model process flow with a gui interface. The flow may include tasks, decisions or calls to other process flows. The saved flow is in a jar file together with its bytecode.

JFormulaEngine is a formula engine that runs spreadsheet-style formulas in any context. The function library is fully extensible and the engine can resolve variable names to any context, such as a CMS or spreadsheet, that is supported by JFormulaEngine.

JavaCET is an API wrote in Java that allows to analyze Java source code and libraries, and control its execution and its trace in an integrated and comprehensible object-oriented way. It allows backwards execution.

OpenL implements Java-like languages allowing to use code snippets placed in Excel, XML, or DB. OpenL is a foundation for OpenRules http://openrules.com. Maintained from http://openl.org

mojo is a standalone software and library for the fast analysis of business processes. Because of its lightweight architecture and its implementation in Java, it can be used as extension in your program, e.g., business process designer. It provides new researched compiler-based analysis techniques which supports very good failure location. The software can be used under the GNU Lesser General Public License (LPGL): http://www.gnu.org/licenses/lgpl-3.0.txt
