I am experiencing the following issue while running my tests. However, it only happens when I am using @DataProvider with a @Test that has invocation count greater than 1. I am not sure if the following link below is the same issue, because if I read correctly this issue has already been fixed in higher versions of the Eclipse TESTNG plugin 6.9.13.X (using this 6.9.14.201610261028).
Here is a simple code that is encountering the same problem:
@Test(dataProvider = "data", timeOut = 6000, threadPoolSize = 10, invocationCount = 5)
public final void x(String a,
String b, String c, String d,
String e, String f, String g){
System.out.println("D"
+ " - "
+ java.lang.Thread.currentThread().getId()
+ " - "
+ new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS")
.format(new Date()));
}
Here is a sample output:

Sometimes it will also throw the following exceprions:
