Issue/Introduction

Infrastructure Agents (IA) monitoring Kafka via JMX fail to establish a connection following an agent restart.

Behavior: The initial connection succeeds when the user manually configures the password in plain text. However, upon agent restart, the stored password gets automatically encrypted.

Once encrypted, the JMX client fails to process the credential properly, leading to authentication failures.

The following errors are observed in the IntroscopeAgent.log after restarting the agent:

[ERROR] [IntroscopeAgent.JMXClient] JMX Connection Failed to Server ###:9000
[DEBUG] [IntroscopeAgent.JMXClient] Authentication failed! Invalid username or password
[DEBUG] [IntroscopeAgent.JMXClient] java.lang.SecurityException: Authentication failed! Invalid
