The Java programming language Compiler Group

This group is comprised ofdevelopers involved in the design, implementation, and maintenanceof thejavac compiler for the Java programming language,and associated components such asjavadoc andjavap.

Introduction

Thejavac compiler reads source files written in theJava programming language, and compiles them into class files. TheJava programming language is defined byTheJava Language Specification (JLS) and class files are definedbyTheJava Virtual Machine Specification (JVMS).

Optionally, the compiler can also process annotations found insource andclass files using thePluggable Annotation Processing API (JSR 269).

The compiler is a command-line tool but can also be invokedusing theJava Compiler API (JSR 199).

Source Code

Thejavac compiler source code is available in theOpenJDK repositories, athttps://git.openjdk.org/.

The mainline sources are inhttps://git.openjdk.org/jdk.

For general information about the OpenJDK repositories, and howto clone them, seeThe OpenJDKDeveloper's Guide.

Note that the code for the native launcher forjavac isshared with all the other JDK tools, and is customized forjavac during the build.

Issues

Issues are tracked in theJDKBug System. Most compiler bugs are tracked in thetools component,javac subcomponent.
