Resolution:

  

1)      1) Check the JDK Requirement of the JDeveloper version which is to be installed. Eg. As per Oracle documentation for Jdev 11.1.1.6.0 the JDK shall be JDK_6.0_27 or above.

2)       2) Check the server jdk version.To do the same t go to location WL_HOME/common/bin/commEnv.cmd ad Look for lines like the ones below (examples are from a WLS install on a Unix machine)

#JAVA_USE_64BIT, true if JVM uses 64 bit operations.

3)      3) Install JDK version which is either server version or lower than that version and then build/migrate your service.
