Looks like call stack info of the exception is not produced for OPTIONAL login module when debug is on. Here : https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/javax/security/auth/login/LoginContext.java#L877 we don't dump call stack for exception thrown when manually the credentials are supplied. So we don't get what we are expecting in out output stream.

But when we use Unix/NT Login module which uses gid and uid to verify the login then already the test case dumps the stack trace: https://github.com/openjdk/jdk/pull/9159/files#diff-455563a58230c5d5d6e24f73ab094d4d7572dc2c2771e3db70feb53c7d9b3a18R78
