On Oracle Metalink this error is solved: note: 471035.1
There has been a problem with the orabpel.ear file in some environments. The issue
can be verified by checking the size of the orabpel.ear files in the the following locations

$ORACLE_HOME/bpel/system/services/lib

and

$ORACLE_HOME/j2ee/oc4j_soa/applications

If only one of them is of size 2530260 bytes, then you have hit upon the cause for this issue in your environment.

Solution
Copy the orabpel.ear from $ORACLE_HOME/bpel/system/services/lib (the one that is of size 2530260 bytes) to the location
$ORACLE_HOME/j2ee/oc4j_soa/applications (to replace the one that is not 2530260 bytes) and restart.
