[jira] [Commented] (DERBY-6981) SQLSTATE: XJ001, SQLERRMC: java.lang.NullPointerExceptionXJ001.U

    [ https://issues.apache.org/jira/browse/DERBY-6981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16346277#comment-16346277 ] 

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.
