Package org.jboss.weld.bean.proxy.util

Class WeldDefaultProxyServices

java.lang.Object

org.jboss.weld.bean.proxy.util.WeldDefaultProxyServices

All Implemented Interfaces:

org.jboss.weld.bootstrap.api.Service, org.jboss.weld.serialization.spi.ProxyServices

public class WeldDefaultProxyServices
extends Object
implements org.jboss.weld.serialization.spi.ProxyServices

This class is a default implementation of ProxyServices that will only be loaded if no other implementation is detected. It is only used up until JDK 11 at which point it is replaced by its alternative implementation.

This class cracks open the class loader's defineclass method and then uses it to define new classes.

Method Detail

makeClassLoaderMethodsAccessible

public static void makeClassLoaderMethodsAccessible()

This method cracks open ClassLoader#defineClass() methods by calling setAccessible().

It is invoked during WeldStartup#startContainer() and only in case the integrator does not fully implement ProxyServices.
