Java library implementing the Dependency Injection pattern

 PicoContainer is a highly embeddable full service Inversion of Control
 (IoC) container for components honour the Dependency Injection pattern.
 It can be used as a lightweight alternative to Sun's J2EE patterns for
 web applications or general solutions.
 .
 Despite it being very compact in size (the core is ~128K and it has no
 mandatory dependencies outside the JDK), PicoContainer supports
 different dependency injection types (Constructor, Setter, Annotated
 Field and Method) and offers multiple lifecycle and monitoring
 strategies.
