[RIVER-415] Non-forward compatible code leads to RuntimeException when accessing class com.sun.jini.logging.Levels

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: jtsk_2.1, River_2.2.0
• Component/s: com_sun_jini_logging

Environment

Oracle JDK 1.6.0_38 or higher; 1.7.0_13 or higher

Workaround

Run against a JDK version which matches the expected serialization format; or patch the local version of Levels to match the expected format.

A fuller fix needs more complicated serialization/deserialization code to create a Level object.

Description

With Oracle JDK 1.6.0_38 and JDK 1.7.0_13, Oracle added an extra field (localizedLevelName) to java.util.logging.Level.

com.sun.jini.logging.Levels contains some code which depends on knowing the serialization format of the JDK class and crashes with the below exception when attempting to upgrade JDK version.
