It is possible to limit the number of installed bundles, registered services and listeners as defined in the OSGi Framework Specification.

These limits take effect when the following methods are invoked:

• BundleContext.installBundle – If the bundles limit is reached and the bundle is not already installed, a BundleException is thrown.
• BundleContext.registerService – If the services limit is reached, an IllegalStateException is thrown.
• BundleContext.addXxxListener – If the listeners limit is reached, an IllegalStateException is thrown.

The number of bundles, services and listeners are respectively defined with the mbs.bundle.count, mbs.service.count and mbs.listener.count system properties. By default, no limits are imposed.
