After upgrading Oracle EBS from 12.1.3 to 12.2 when we go to Oracle and open an Invoices screen we get the following error :
FRM-92101: There was a failure in the Forms Server during startup. This could happen due to invalid configuration. Please look into the web-server log file for details.

Java Exception: oracle.forms.net.ConnectionException: Forms session <16> aborted: unable to communicate with runtime process. at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source) at oracle.forms.net.HTTPNStream.getResponse(Unknown Source) at oracle.forms.net.HTTPNStream.doFlush(Unknown Source) at oracle.forms.net.HTTPNStream.fiush(Unknown Source) at javaio.DataOutputStream.flush(Unknown Source) at oracle.forms.net.StreamMessageWriter.run(Unknown Source)
