Reason(s): Evaluations must contain either an expression or a block of well-formed statements (In reply to Sarika Sinha from comment #1) I wasn't clear about this: The code shown should go into a Java file in a project project, and the error message shows up in the log of the debugger, not in the debug expressions view. I can confirm this issue. This is a major impediment to my debugging workflow.
I see this issue when I set a breakpoint in a javax.swing package. When that breakpoint hits and I try to use the Debug Shell window to execute statements, the Debug Shell prints:
"Evaluations must contain either an expression or a block of well-formed statements"
The Error Log has an entry that shows:
"Compile error during code evaluation: The package javax.swing is accessible from more than one module: <unnamed>, java.desktop"
I use this feature to debug things happening inside of Java's libraries.

Steps to reproduce Make a Java project with a module-info, add a breakpoint at StringBuilder.append(String), start debugging, and try to evaluate anything. void main(String args[]) { System.out.println("Hello, " + args[0]); } You'll get the error: "The package java.lang is accessible from more than one module: java.base, Xxx" (Not related to lambdas specifically, by the way, caused by trying to compile an expression in an imported package, as fas as I can tell)
