Knut Anders Hatlen commented on DERBY-5335:
-------------------------------------------

FWIW, the test passes when run standalone in my environment (Solaris 11 Express, Java 6):

$ java -Xmx512m  junit.textui.TestRunner org.apache.derbyTesting.functionTests.tests.lang.XplainStatisticsTest
.......................
Time: 53.556

OK (23 tests)

> I ran the test standalone because I wanted to figure out why the following example fails
for me. I thought that this example would work based on the documention in the Reference Guide
