Bryan Pendleton commented on DERBY-6981:
----------------------------------------
I took the provided derby-test.java and tweaked it slightly. I ran it as
follows:
javac -cp .;\users\bryan\derby\trunk\classes test1.java
java -cp .;\users\bryan\derby\trunk\classes test1
It produced the following output:
Insert 3
3: 1517299200000 -> 1517376190493
I'm not really sure what the program was supposed to do, but it didn't produce
a NullPointerException for me.
However, an important difference is that I ran the program in Embedded mode,
not in Client/Server mode.
