Legman

Legman is a fork of the Guava Eventbus.

Differences to Guava

• weak references by default
• synchronous and asynchronous dispatching in same EventBus
• all options are controlled by attributes of the subscribe annotation
• exceptions are propagated to caller (works only with synchronous dispatching)

In addition, Legman comes with ready to use integrations:

• Apache Shiro
• Google Guice
• Micrometer
