NPE 10.1.3.1 - Can you solve it?

Question

I get an NPE in OC4J 10.1.3.1 that I did not get in OC4J 9.0.4.
The easisest way to explain it that it seems that a ResultSet that is populated in a bean, via JSP javascript invocation, is "lost" once that same JSP attempts to access it for display.
You will see by my debug statements that ResultSet is populated (in SQLDataSource.java) with 1902 rows. I have commented out debug statements that I previoulsy executed to access the ResultSetMetaData and that is all in tact. Further, I even debugged the getString in the that same code and found it to be in tact.
First I'll give you the trace and then I'll provide the JSPs java file where the error is on line 66 as:
out.print( detail.getString("ACCT") );
All of this is followed by links to view all pertinent code:
