ArrayList get(int) Object Error

[SusOperator]

Error produced in debugger Breakpoint condition 'test.get(0).get(0).equals("Work0")' error: Cannot evaluate because of compilation error(s): The method get(int) is undefined for the type Object.

Breakpoint created on line with System.out.println("End") used in debugger test.get(0).get(0).equals("Work0")

Consolidated code import java.util.ArrayList;

public class ArrayList2D { public static void main(String[] args) { ArrayList<ArrayList<String>> test = new ArrayList<ArrayList<String>>(); ArrayList<String> subTest = new ArrayList<String>(); subTest.add("Work0"); subTest.add("Work1"); subTest.add("Work2"); test.add(subTest); System.out.println("Full ArrayList: " + test); System.out.println("Targetted location of ArrayList: " + test.get(0).get(0)); if (test.get(0).get(0).equals("Work0")) { System.out.println("Breakpoint should work!"); } System.out.println("End"); } }

Code Output without Debugger Full ArrayList: [[Work0, Work1, Work2]] Targetted location of ArrayList: Work0 Breakpoint should work! End

Environment

• Operating System: Windows 10 x64
• JDK version: JDK 13.0.2
• Visual Studio Code version: 1.51.1
• Java extension version: 0.12.0
• Java Debugger extension version: 0.29.0

Steps To Reproduce

1. Run consolidated code
2. Setup a breakpoint at the End printout with test.get(0).get(0).equals("Work0")

Current Result

test.get(0).get(0): Cannot evaluate because of compilation error(s): The method get(int) is undefined for the type Object.

Expected Result

test.get(0).get(0): "Work0"

Additional Information

I have a program that uses 2D ArrayLists, and I commonly will track down issues utilizing the debugger. I have not used the debugger in a few months, but since I came back to my setup (same breakpoints as before) the debugger has changed behavior.
