This is the project home for the backport175 project.

backport175 is backport of the Java 5 annotations (JSR-175) specification. Making strongly typed annotation available for Java 1.3/1.4 platforms. They are bytecode compatible with Java 5 annotations making them available for use by tools etc.

backport175 is Open Source and freely available under Apache License Version 2.0.

It has two separate modules:

• Compiler - which compiles the backport175 annotations and puts them into the bytecode of the class (compatible with regular Java 5 RuntimeVisible annotations).

• Reader - which allows you to read the backport175 annotations as well as regular Java 5 annotation through one single uniformed API. The reader also has an API for runtime management, which allows you to update the bytecode at runtime and have your changes propagated.

It also comes with an Ant task, an Eclipse plugin and an IDEA plugin.
