JOC Cockpit should not throw Exception if only one of Keystore or Truststore is configured

Current Situation

• JOC Cockpit raises the "ava.lang.IllegalStateException: KeyManagerFactoryImpl is not initialized" if only a Keystore or only a Truststore is configured with the joc.properties file. 
• Users, who do not make use of a truststore configured with the joc.properties file are affected by this error:
  • Releases prior to 2.8.1 fall back to using the cacerts truststore provided by Java.
  • Release 2.8.1 does not use a default truststore if the setting is not used.

Desired Behavior

• JOC Cockpit should not throw an IllegalStateException if only a Keystore is configured in the joc.properties file.
• JOC Cockpit should fall back to using the cacerts truststore provided by Java.

Workaround

• Users who did not use the truststore setting can configure the truststore in the joc.properties file like this:

  • truststore_path = C:\\ProgramFiles\\Java\\jdk21.0.6_7\\lib\\security\\cacerts 
    truststore_type = PKCS12 
    truststore_password = changeit 
    

• • The truststore_path setting must be adjusted to the related location of Java.
  • The truststore_type makes use of the constant value PKCS12.
  • The indicated truststore_password is the default used by every Java version.
