Description

On converting LobLimits.java to LobLimitsTest I noticed this disabled test:
There is disabled test in largedata.LobLimitsTest.java which is a carryover from largedata.LobLimits.java

// Disabled for now, this will materialize, will open
// jira for it.
// updateClob2("ClobTest #8.1",conn,selectClob,BIG_LOB_SZ,0,0,10,1,CHARDATAFILE);

Enabling the test for embedded I noticed it still can get an out of memory. (I actually think I did run it once successfully)
but on my second full run of the suite I saw it fail.

The test passes on client and in LobLimitsLiteTest in embedded. To reproduce run largedata.LobLimitsTest, commenting out the below condition:
if (!(usingEmbedded() && BIGGEST_LOB_SZ == _2GB))

{ updateClob2("ClobTest #8.1",selectClob,BIG_LOB_SZ,0,0,10,CHARDATAFILE); }

or likely you can get a smaller standalone test case by adjusting the sizes and adjusting down the heap with -Xmx
