aggregateOptimization.sql fails on z/os with  pmz3160sr5 with double quote and question mark
output in runtime statistics

            Reporter: Kathey Marsden
            Priority: Minor


With this one test and  pmz3160sr5-20090604_01(SR5) the output  of runtime statistics has
double quote and question mark garbage, e.g

Source result set:
""""????"Scalar Aggregate ResultSet:
""""????"Number of opens = 1
""""????"Rows input = 1
"       ""????"constructor time (milliseconds) = 0
"       ""????"open time (milliseconds) = 0
"       ""????"next time (milliseconds) = 0
"       ""????"close time (milliseconds) = 0
"       ""????"optimizer estimated row count:           15.00
"       ""????"optimizer estimated cost:           21.13

""""????"Index Key Optimization = true
""""????"Source result set:

Looking manually at the plans, they look fine.  I  think this is likely a JVM issue, but don't
know actually if it is impacting the test harness, ij, or derby itself.   I did not see this
with the 64 bit sr5 jvm, nor did I see it in 10.5 runs with earlier versions of the jvm.
