/**
* 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-jakartaee profile, it uses {@link org.glassfish.weld.ACLSingletonProvider}.
* It tests profile by testing existence of
* {@link org.glassfish.javaee.full.deployment.EarClassLoader}.
* <p>
* 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 Jakarta EE app.
* <p>
* The bundle activator resets the SingletonProvicer in stop().
