Hi
I am using soot to find the returned value of each method in the following
jimple file. it is very wired, besides the method "execute", there is
another method called "class$", which returns "r0", the signature is "<
com.oreilly.struts.storefront.security.LoginAction: java.lang.Class class$(
java.lang.String)>". Because this method is useless for my analysis, can I
filter out it using some methods?

public class com.oreilly.struts.storefront.security.LoginAction extends
com.oreilly.struts.storefront.framework.StorefrontBaseAction
{
    protected static org.apache.commons.logging.Log log;
    static java.lang.Class class$0;

    static void <clinit>()
    {
        java.lang.Class $r0;
        java.lang.NoClassDefFoundError $r1;
        java.lang.ClassNotFoundException $r2;
        java.lang.String $r3;
        org.apache.commons.logging.Log $r4;

        $r0 = <com.oreilly.struts.storefront.security.LoginAction:
java.lang.Class class$0>;
        if $r0 != null goto label3;

     label0:
        $r0 = staticinvoke <java.lang.Class: java.lang.Class forName(
java.lang.String)>("
com.oreilly.struts.storefront.framework.StorefrontBaseAction");

     label1:
        <com.oreilly.struts.storefront.security.LoginAction:
java.lang.Classclass$0> = $r0;
        goto label3;

     label2:
        $r2 := @caughtexception;
        $r1 = new java.lang.NoClassDefFoundError;
        $r3 = virtualinvoke $r2.<java.lang.Throwable:
java.lang.StringgetMessage()>();
        specialinvoke $r1.<java.lang.NoClassDefFoundError: void <init>(
java.lang.String)>($r3);
        throw $r1;

     label3:
        $r4 = staticinvoke <org.apache.commons.logging.LogFactory:
org.apache.commons.logging.Log getLog(java.lang.Class)>($r0);
        <com.oreilly.struts.storefront.security.LoginAction:

        return;

        catch java.lang.ClassNotFoundException from label0 to label1 with
label2;
    }
