Steps to reproduce issue
========================
1. Create a schema XXXXXX, YYYYYY.
2. Create the table VF_SYN_TEST in that schema and give permissions:

  CREATE TABLE "XXXXXX"."VF_SYN_TEST"
  ( "VF_SYN_TEST_ID" NUMBER(10,0),
  "DETAILS" VARCHAR2(100 BYTE) NOT NULL ENABLE,
  "DATE_INSERTED" DATE DEFAULT SYSDATE,
  CONSTRAINT "PK_VF_SYN_TEST" PRIMARY KEY ("VF_SYN_TEST_ID")
  );
  grant all on VF_SYN_TEST to YYYYYY;
3. Log into a schema YYYYYY.
4. Create a synonym for the table:
CREATE OR REPLACE SYNONYM "YYYYYY"."VF_SYN_TEST" FOR
"XXXXXX"."VF_SYN_TEST";
5. Create a WebLogic domain with a datasource pointing at schema YYYYYY.
6. Any application on using this synonym table will fail.
