Created attachment 151678 [details] Testcase Lets say there is a select query which returns a clob as one of the column. If this clob is returned after some PL/SQL manipulation, i.e it should be a temporary clob, it results in OutofMemoryError. As the value is converted to char[] or byte[] before returning, user doesn't have reference to it, they cannot call freeTemporary() method to release its memory. So, eclipselink needs to identify temporary LOBs and free them. To reproduce the issue. 1. Import attached project LOBTest in Eclipse. 2. Run script create.sql in oracle database. 3. Insert big clob values in person2 table. 4. Run Junit testcase test.Bug8673104Test.
Created attachment 151679 [details] Proposed Solution Bug8673104.diff is the proposed solution to free up the memory by calling freeTemporary() method on LOBs if LOB is temporary object.
