Myrna van Lunteren reopened DERBY-6311:
---------------------------------------


I mistakenly resolved this as a duplicate.
On closer look, this is a different stack trace.

I believe the 'connection reset' of DERBY-6143 was actually a machine-specific 
problem which exhibited itself in other tests, but only on the 10.10 windows 
test machine, and this is a different problem. Mike did notice that the stack 
trace was different after the move of the tests to another machine.

I think the last several occurrences of failures in this same test have been 
incorrectly attributed to the connection reset issue, at least this is true for 
these occurrences:
- February 21, 2013 - 10.9 branch, (10.9.2.2 - (1448885)), with ibm 1.7 see:
  
http://people.apache.org/~myrnavl/derby_test_results/v10_9/windows/testlog/ibm17/1448885-suites.All_diff.txt
- May 2: (caused by a java.io.UTFDataFormatException), trunk, 10.11.0.0 alpha - 
(1478624), ibm 1.6:
  
http://people.apache.org/~myrnavl/derby_test_results/main/windows/testlog/ibm16/1478624-suites.All_diff.txt
Failed on may 27th after the machine move, trunk, windows, ibm17
http://people.apache.org/~myrnavl/derby_test_results/main/windows/testlog/ibm17/1486723-suites.All_diff.txt
also failed on may 30th, trunk, windows ibm17:
http://people.apache.org/~myrnavl/derby_test_results/main/windows/testlog/ibm17/1488075-suites.All_diff.txt
failed in 10.10, windows, ibm16
http://people.apache.org/~myrnavl/derby_test_results/v10_10/windows/testlog/ibm16/1485921-suites.All_diff.txt
another occurrence of intermittent error: 10.10, windows, ibm15
http://people.apache.org/~myrnavl/derby_test_results/v10_10/windows/testlog/ibm15/1491324-suites.All_diff.txt

I'll close off the other issue as cannot reproduce.
