Wrong reported errors by compiler

I have some pieces of code that compiles fine in IntelliJ and Gradle but VSCode reports them as errors.
Examples:

1. Error in import

   import sun.security.ssl.ProtocolVersion;

I have to point that I'm not using the JVM in the error description. Here's my workspace's settings:

{
   "java.home": "/Users/augusto.dias/.sdkman/candidates/java/8.0.181-oracle",
   "java.jdt.ls.vmargs": "-javaagent:/Users/augusto.dias/my-project/.vscode/lombok.jar -Xbootclasspath/a:/Users/augusto.dias/my-project/.vscode/lombok.jar"
}

2. Wrong exception handling

I have a RetryTemplate class from spring and I'm calling execute as the following example:

retryTemplate.execute(getCallback(),getRecovery());

private RetryCallback<Void, IOException> getCallback() {
    return context -> {
        if (context.getLastThrowable() instanceof IOException) {
                    IOException e = (IOException) context.getLastThrowable();
    // do some other things
                    throw e;
        }
        return null;
    };
}

private RecoveryCallback getRecovery() {
    return context -> {
        Throwable lastThrowable = context.getLastThrowable();
    // do some other things
        throw lastThrowable instanceof Exception ? (Exception) lastThrowable : new Exception(lastThrowable);
    }
}

3. And finally: false error in method signature

    assertThat((List) ((Envelope) responseEntity.getBody()).getData(), hasItems(siteDTO));
    assertThat((List) ((Envelope) responseEntity.getBody()).getData(), hasSize(1));

Environment

• Operating System: macOS Mojave
• JDK version: 1.8
• Visual Studio Code version: 1.29.1
• Java extension version: 0.34.0

Inizia riproducendo le tre diagnosi segnalate nei frammenti Java forniti usando le impostazioni dell'area di lavoro, JDK 1.8, VS Code 1.29.1 e Java extension 0.34.0. Confronta i risultati del language server con IntelliJ e Gradle, quindi determina se ogni errore falso ha la stessa causa. Il lavoro è completato quando gli esempi interessati non producono più diagnosi errate e sono presenti test di regressione per i casi segnalati.
