Hi,

Seem to be related to the java version.

If you google "Unsupported major.minor version 52.0" you find many references explaining the case.

Making it short you are trying to run a piece of java compiled with a version (1.8 I would say) but you run it with a lower java version.

11g java version is "1.7.0_79" and 12c version is "1.7.0_75" , do we need to consider only 1.7.0 or 1.7.0_x also for comparing java versions.

As @Gianni mentioned, for OBIEE 12c, you need a 1.8 JDK. - Oracle Fusion Middleware Supported System Configurations

Hi.,

I am getting below error during 11g export using migration_tool.jar

"An error occurred during export: java.lang.RuntimeException

Migration action failed: java.lang.NullPointerException" ,

Joel Acha

Have you upgraded your JDK on OBIEE 12c to a 1.8 version?

Rajagopal R-Oracle

yes both 11g and 12c having same JDK version.

Joel Acha

look at this Oracle document and ensure you're passing the correct parameters in your call to the migration tool - https://blogs.oracle.com/pa/resource/11g12cUpgradeTips.ppt
