AspectJ tools most notably contains the AspectJ compiler (AJC). AJC applies aspects to Java classes during compilation, fully replacing Javac for plain Java classes and also compiling native AspectJ or annotation-based @AspectJ syntax. Furthermore, AJC can weave aspects into existing class files in a post-compile binary weaving step. This library is a superset of AspectJ weaver and hence also of AspectJ runtime.

There is a newer version: 1.9.22.1

/**
 * Simple implementation if the registry support functionality.
 * The logging output is done onto System.out (for both specific and generic logs)
 * in the following format:
 *
 * [Error|Warning|Log]: Main error message
 * [Error|Warning|Log]: Child error message 1
 * 	...
 * [Error|Warning|Log]: Child error message N
 *
 * The translation routine assumes that keys are prefixed with '%'. If no resource
 * bundle is present, the key itself (without leading '%') is returned. There is
 * no decoding for the leading '%%'.
