Debugging in one-line lambdas does not work

[fhuonder]

Hi

My versions:

• vscode: 1.99.2
• vscode-java-debug: 0.58.1
• Language Support for Java(TM) by Red Hat: 1.41.1
• JDK 24
• vscode devcontainer
• Maven project

I cannot debug one-line lambdas.

This is how the code looks like as soon as I start the application:

As you can see, the two breakpoints where the lambda is a one-liner are grayed out (unverified breakpoint).
The execution does not stop there but it stops at the other breakpoints.
The one-liner breakpoints are created as inline breakpoints.

My assumption is that this is a bug.

Here the code to take and paste somewhere:

public String createMessage() {
    return Stream.of("Hello", " World", " - ", "What's", " up?")
    .map(token -> token + "1")
    .map(token -> {return token + "2";})
    .map(token -> {
        String result = token.substring(0, token.length() - 2);
        return result;
    })
    .collect(Collectors.joining());
}

Would be nice if this could be fixed or if someone can tell me what I'm doing wrong.

@fhuonder can you recheck this issue? I can hit the breakpoints.
