WEIRD PROBLEMS, Re: Front-ending Java for RPG -- Anybody here familiar with it besides Scott?

Yesterday, right before leaving for a concert (Perlman in recital, at
Disney Hall), I wrote:

I find that I get the primary key information, but then the
jdbc_freeResult(rs) call blows up. I've got dumps, and I can do
something with them tomorrow morning.

Not quite sure what to make of the dumps, but here is what shows up in the joblog of my terminal session:

Object domain or storage protection error for offset X'00000000838D0088'

Scott's JDBC_ExecQry looks like:

P JDBC_ExecQry B export
D JDBC_ExecQry PI like(ResultSet)
D conn like(Connection) const
D sql 32767A varying const options(*varsize)
D stmt s like(Statement)
D temp s like(ResultSet)
D rs s like(ResultSet)
/free
jdbc_begin_object_group(50);

monitor;
stmt = createStatement( conn );
temp = executeQuery( stmt : s(sql));
jdbc_end_object_group(temp: rs);
on-error;
jdbc_end_object_group();
return *NULL;
endmon;

return rs;
/end-free
P E

and my JDBC_GetPrimaryKeys looks like:

P JDBC_GetPrimaryKeys...
P B export
D JDBC_GetPrimaryKeys...
D PI like(ResultSet)
D dbmd like(DatabaseMetaData) const
D catalog 32767A varying const options(*varsize)
D schema 32767A varying const options(*varsize)
D table 32767A varying const options(*varsize)
D temp s like(ResultSet)
D rs s like(ResultSet)
D cat s like(jString)
D sch s like(jString)
/free
jdbc_begin_object_group(50);
if (catalog = '*NULL');
cat = *NULL;
else;
cat = s(catalog);
endif;
if (schema = '*NULL');
sch = *NULL;
else;
sch = s(schema);
endif;
monitor;
temp = getPrimaryKeys(dbmd: cat: sch: s(table));
jdbc_end_object_group(temp: rs);
on-error;
jdbc_end_object_group();
return *NULL;
endmon;

return rs;
/end-free
P E

Any clues there?
