The largest message in the 14 rows is 2702475 according to LENGTH(MESSAGE), so even though
ij is doing a getString() and materializing the CLOB I am surprised it is running out of memory
with a less than 3MB CLOB.

As an aside, for jdk 1.6 where it can call free,  maybe it would make sense for ij to do 
a getSubString on CLOBS for only the amount it plans to display insted of a getString() to
get the whole thing. I still don't think in this case it should run out of memory with this
size CLOB unless I have slipped a digit which is not uncommon.
