Unexpected 'java.lang.StackOverflowError' exception in TokenCache.java class

[narayanagowdas]

Hi,

I'm getting 'java.lang.StackOverflowError' exception from authenticationResult.account() when both accountCacheEntity and account are null;

microsoft-authentication-library-for-java/src/main/java/com/microsoft/aad/msal4j/TokenCache.java

Line 237 in 6b18408

if (authenticationResult.account() != null) {

Scenario causing the issue is,

• Trying to fetch token using ConfidentialClientApplication acquireToken(ClientCredentialParameters parameters) method.

• Able to successfully fetch the token by passing ClientCredentialParameters. Responses received are
  httpResponse :{"token_type":"Bearer","expires_in":3600,"ext_expires_in":3600,"access_token":"<ACTUAL_TOKEN>"}
  TokenResponse : tokens = {"access_token":"<ACTUAL_TOKEN>","id_token":"","token_type":"Bearer","expires_in":3600}

• The AuthenticationResult received in the TokenRequest.java class contains valid values for "accessToken", "extExpiresOn", "expiresOn" and "environment". All other fields including accountCacheEntity and account are null.
  

  microsoft-authentication-library-for-java/src/main/java/com/microsoft/aad/msal4j/TokenRequest.java

  Line 113 in 6b18408

  return result;

• When accountCacheEntity and account is null, authenticationResult.account() in the TokenCache.java class is throwing 'java.lang.StackOverflowError' for account field.

Is this an open issue? or please let me know if I am missing something. Thanks in advance.

account field is "lazy" initialized, so IDE can not evaluate it, null will be returned if you actually call it
