But this does not occur each time i run the program, this is randomly happening with me.

Code through which this issue is happening is as follows:

 

public static void main(String[] args) {

int counter = 10;
for(int index = 0; index < counter; index++)

{ System.out.println("*** Iteration " + (index+1) + " ***"); DataAccessJDBC access = new DataAccessJDBC (); access.runCRUD(); }

private void runCRUD() {
Connection conn = null;

try

{ conn = initConnection(); setProjectQuery(conn); Long start = Instant.now().getEpochSecond(); insertTableA(conn); insertTableB(conn); insertTableC(conn); insertTableD(conn); Long end = Instant.now().getEpochSecond(); System.out.println("Total time in seconds: "+(end-start)); }

catch (Exception e)

{ e.printStackTrace(); }

finally

{ closeConnection(conn); }

}

}

 

Any suggestion/recommendation to fix this, i tried with teiid version 9.0.1 and with version 15.0.0 as well.

Thanks
