org.apache.aries.proxy.impl.common.OSGiFriendlyClassWriter

public final class OSGiFriendlyClassWriter
extends org.objectweb.asm.ClassWriter

We need to override ASM's default behaviour in getCommonSuperClass(String, String) so that it doesn't load classes (which it was doing on the wrong ClassLoader anyway...)

Method Detail

getCommonSuperClass

protected final String getCommonSuperClass(String arg0,
                                           String arg1)

We provide an implementation that doesn't cause class loads to occur. It may not be sufficient because it expects to find the common parent using a single classloader, though in fact the common parent may only be loadable by another bundle from which an intermediate class is loaded precondition: arg0 and arg1 are not equal. (checked before this method is called)
