JGRP000225: failed unmarshalling buffer into return value: NPE (ASYM_ENCRYPT + TCP, during server startup)

    XMLWordPrintable

Details

    • Bug
    • Resolution: Done
    • Major
    • 11.0.0.Alpha1
    • 10.1.0.Final
    • Clustering
    • None
    • Hide

      Can be reproduced locally:
      1. extract two instances of EAP 7.1.0.DR10, modify standalone-ha.xml (see Description)
      2. add a clustered deployment
      3. start the first server with standalone-ha configuration, and after few seconds start the second one
      4. one of the two servers usually logs the NPE

    Description

      Scenario: failover clustering test with enabled "AUTH" and "ASYM_ENCRYPT" protocols + JGroups default stack set to TCP. This issue doesn't occur when using UDP stack.

      Also, encrypt_entire_message needs to be set to "false"

      TCP stack configuration
      <stack name="tcp">
    <transport type="TCP" socket-binding="jgroups-tcp"/>
    <protocol type="MPING" socket-binding="jgroups-mping"/>
    <protocol type="MERGE3"/>
    <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>
    <protocol type="FD"/>
    <protocol type="VERIFY_SUSPECT"/>
    <protocol type="ASYM_ENCRYPT">
      <property name="encrypt_entire_message">false</property>
      <property name="sym_keylength">128</property>
      <property name="sym_algorithm">AES/ECB/PKCS5Padding</property>
      <property name="asym_keylength">512</property>
      <property name="asym_algorithm">RSA</property>
    </protocol>
    <protocol type="pbcast.NAKACK2"/>
    <protocol type="UNICAST3"/>
    <protocol type="pbcast.STABLE"/>
    <protocol type="AUTH"> 
      <property name="auth_class">org.jgroups.auth.MD5Token</property>
      <property name="auth_value">jdgservercluster</property>
      <property name="token_hash">MD5</property>
    </protocol>
    <protocol type="pbcast.GMS"/>
    <protocol type="MFC"/>
    <protocol type="FRAG2"/>
</stack>

      During servers startup, after receiving a new cluster view, one of the servers usually logs this error message:

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-8405 JGRP000225: failed unmarshalling buffer into return value: NPE (ASYM_ENCRYPT + TCP, during server startup)

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
          • Verified
          is blocked by

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. WFLY-7934 Upgrade JGroups to 3.6.13.Final

          is caused by

          Bug - A problem that impairs or prevents the functions of the product. JGRP-2153 Encrypt protocols transform empty buffer into null buffer when encrypt_entire_message is disabled
