OSGI Support

Hazelcast bundles provide OSGI services so that Hazelcast users can manage (create, access, shutdown) Hazelcast instances through these services on OSGI environments. When you enable the property hazelcast.osgi.start (default is disabled), when an Hazelcast OSGI service is activated, a default Hazelcast instance is created automatically.

Created Hazelcast instances can be served as an OSGI service that the other Hazelcast bundles can access. Registering created Hazelcast instances behavior is enabled by default; you can disable it using the property hazelcast.osgi.register.disabled.

Each Hazelcast bundle provides a different OSGI service. Their instances can be grouped (clustered) together to prevent possible compatibility issues between different Hazelcast versions/bundles. This grouping behavior is enabled by default and you disable it using the property hazelcast.osgi.grouping.disabled.

Hazelcast OSGI service’s lifecycle (and the owned/created instances’s lifecycles) is the same with the owner Hazelcast bundles. When the bundle is stopped (deactivated), the owned service and Hazelcast instances are also deactivated/shutdown and deregistered automatically. When the bundle is re-activated, its service is registered again.

The Hazelcast Enterprise JAR package is also an OSGI bundle like the Hazelcast Open Source JAR package.
