/**
* This is a bundle activator which is responsible for configuring Weld bundle
* to be used in GlassFish. As part of configuration, it configures the the
* SingletonProvider in Weld. It sets different SingletonProvider for different
* profiles. e.g., in WebProfile, it sets
* {@link org.jboss.weld.bootstrap.api.helpers.TCCLSingletonProvider}, where as
* for full-javaee profile, it uses
* {@link org.glassfish.weld.ACLSingletonProvider}. It tests profile by testing
* existence of {@link org.glassfish.javaee.full.deployment.EarClassLoader}.
*
* Since Weld 1.1, an implementation of the
* {@link org.jboss.weld.serialization.spi.ProxyServices} SPI is used to provide
* a classloader to load javassist defined proxies. This classloader ensures
* that they can load not only application defined classes but also classes
* exported by any OSGi bundle as long as the operation is happening in
* the context of a Java EE app.
*
* The bundle activator resets the SingletonProvicer in stop().
