History

This parser is based on work by Sreenivasa Viswanadha and Júlio Vilmar Gesser. The original project, now inactive, was originally hosted at Google Code and supported only parsing Java 1.5.

The project now supports parsing Java 1.8 and aims to continue support for features in future versions of the Java language.
