Eclipse Error: java.lang.CharSequence cannot be resolved

Question

I\'m getting a error trying to compile a simple code in Eclipse. I\'m using jre8.

For example, when I try to compile this code:

import java.util.ArrayLis         


        

Answer 1

This is because the BytecodeParser class in soot.JastAddJ doesn't support higher version of java class file format.The CONSTANT_MethodHandle,CONSTANT_MethodType and CONSTANT_InvokeDynamic of constant pool type missed.Below is my solution to fix the question:

(1) add the type int soot.JastAddJ.BytecodeParser:

private static final int CONSTANT_MethodHandle=15;
private static final int CONSTANT_MethodType=16;
private static final int CONSTANT_InvokeDynamic=18;

(2) add 3 classes to support the parse:

in the method parseEntry of soot.JastAddJ.BytecodeParser,add

CONSTANT_MethodHandle_Info, CONSTANT_MethodType_Info, CONSTANT_InvokeDynamic_Info

in the switch case block.

Now,soot can run successfully.
