Describe the bug

I am trying to run the samples like 02.echo-bot.
The echo bot starts up fine.
But, as soon as I send a message to the bot in the Teams app it throws the following error.

java.util.concurrent.CompletionException: java.io.IOException: java.util.concurrent.ExecutionException: com.microsoft.bot.connector.authentication.AuthenticationException: java.util.concurrent.CompletionException: java.lang.NoClassDefFoundError: com/nimbusds/oauth2/sdk/http/CommonContentTypes

Full startup and stack trace attached.
02.echo-bot.stack.trace.txt

I created an echo bot in Visual Studio using C# with the same App Id and Password and it worked as expected and echoed the message.

To Reproduce

Steps to reproduce the behavior:

1. Start the 02.echo-bot.
2. Connect to the Bot via the Teams App and send a message.
3. It throws the error in the attached stack trace.

Expected behavior

Should echo back the message in the Teams App.

@denstren It looks like Java MSAL has a new version that resolves a missing dependency related to nimbusds.

We get this corrected in the next preview, which is coming in a couple of weeks.

Thanks! Updating to MSAL 1.8.1 worked.
