I have a simple Java test case in VS Code that runs fine, but when I try to step through it in debug it shows the error "Failed to launch debuggee VM. Reason: VM exited with status1"?
I have these extensions installed
- Debugger for Java
- Extension Pack for Java Language Support for Java(TM) by Red Hat
- Maven for Java
- Project Manager for Java
- Test Runner for Java
- Remote - SSH
- Remote - SSH: Editing Configuration
- Files Remote Explorer
import org.junit.Assert;
import org.junit.Test;
public class ProgNodeTest {
@Test
public void progNodeShouldBeInitialized() {
ProgNode pn = new ProgNode();
}
}
The TEST RESULTS window shows
The test run did not record any output.
The DEBUG CONSOLE window shows
ERROR: JDWP unable to get necessary JVMTI capabilities.
I found a VS Code log file that might give a hint to the issue.

And the 3-Language Support for Java (Syntax Server).log file shows what might be the cause of the error. This message is not on its project's build path sounds important.
