IBM The affect of the auto-update feature for Oracle JDK 7 on IBM Mobile Foundation, IBM Worklight, IBM Worklight Foundation, and IBM MobileFirst Platform Foundation - United States  NEWS

ABSTRACT
 The IBM Mobile Foundation, IBM Worklight, IBM Worklight Foundation, and IBM MobileFirst Platform Foundation products support Oracle JDK 7, but do not support Oracle JDK 8. 

CONTENT
On Windows operating systems, because the upgrade to Oracle JDK 8 is enabled by default, you might not be aware that the upgrade has occurred. This Oracle JDK 8 issue applies to the Mac OS as well.



SYMPTOM
You might see one of the following messages in the log file on Windows and Mac OS machines that originate from the WebSphere Application Server Liberty Profile: 

 * TRAS0033E: Runtime injection of detailed method trace failed for class <class name> with exception <exception name> 
 * CWWKC0044W: An exception occurred while scanning class and annotation data. 


RESOLUTION
As stated on the Java SE at a Glance [http://www.oracle.com/technetwork/java/javase/overview/index.html] page, Oracle is automatically migrating users with the auto-update feature enabled from Oracle JDK 7 to Oracle JDK 8. However, a number of IBM and third-party dependencies for IBM Mobile Foundation, IBM Worklight, IBM Worklight Foundation, and IBM MobileFirst Platform Foundation do not support Oracle JDK 8.
