The following issue impacts the copy of BCEL included with our copy of jaxp. This bug report is to include the fix for this issue into the JDK.

[ Bug 39695 - java.lang.ClassFormatError: LVTT entry for 'local' in class file org/shiftone/jrat/test/dummy/CrashTestDummy does not match any LVT entry ]
https://issues.apache.org/bugzilla/show_bug.cgi?id=39695

Simple test case:
=== TestCase.java
import com.sun.org.apache.bcel.internal.classfile.ClassParser;
import com.sun.org.apache.bcel.internal.classfile.ConstantClass;
import com.sun.org.apache.bcel.internal.classfile.ConstantPool;
import com.sun.org.apache.bcel.internal.classfile.ConstantUtf8;
import com.sun.org.apache.bcel.internal.classfile.JavaClass;
import com.sun.org.apache.bcel.internal.classfile.Method;
import com.sun.org.apache.bcel.internal.generic.ClassGen;
import com.sun.org.apache.bcel.internal.generic.MethodGen;

import java.util.ArrayList;
import java.io.FileOutputStream;

class TestCase {
    public static void main(String[] args) throws Exception {
        transform();
    }

    private static void transform() throws Exception {
        JavaClass jc = new ClassParser("TestCase.class").parse();
        //rename class
        ConstantPool cp = jc.getConstantPool();
        int cpIndex = ((ConstantClass)cp.getConstant(jc.getClassNameIndex())).getNameIndex();
        cp.setConstant(cpIndex, new ConstantUtf8("NewTestCase"));
        ClassGen gen = new ClassGen(jc);
        Method[] methods = jc.getMethods();
        int index;
        for (index = 0; index < methods.length; index++) {
            if (methods[index].getName().equals("doSomething")) {
                break;
            }
        }
        Method m = methods[index];
        MethodGen mg = new MethodGen(m, gen.getClassName(), gen.getConstantPool());
        gen.replaceMethod(m, mg.getMethod());
        gen.getJavaClass().dump(new FileOutputStream("NewTestCase.class"));
        Class.forName("NewTestCase");
    }

    public void doSomething(double d, ArrayList<Integer> list) {
    }
}
