ATU Reports throws NullPointerException - selenium-webdriver

Question

I am trying to use ATU Reports for my project. The suite has around 25 #Test methods. After the completion of execution, a null pointer exception is got.
Exception in thread "main" java.lang.IllegalStateException:
java.lang.NullPointe rException

Another observation is that the ATU report is generated successfully when the #Test methods is around 5. Could it be that a particular #Test method is causing this NullPointerException?
testng.xml file is as below:

Something is null in this code (decompiled from ATU 5.1.1):
public void onFinish(ISuite paramISuite)
{
try
{
this.iSuite = paramISuite;
String str1 = SettingsFile.get("passedList") + this.passedTests.size() + ';';
String str2 = SettingsFile.get("failedList") + this.failedTests.size() + ';';
String str3 = SettingsFile.get("skippedList") + this.skippedTests.size() + ';';
SettingsFile.set("passedList", str1);
SettingsFile.set("failedList", str2);
SettingsFile.set("skippedList", str3);
HTMLDesignFilesJSWriter.lineChartJS(str1, str2, str3, this.runCount);
HTMLDesignFilesJSWriter.barChartJS(str1, str2, str3, this.runCount);
HTMLDesignFilesJSWriter.pieChartJS(this.passedTests.size(), this.failedTests.size(), this.skippedTests.size(), this.runCount);
generateIndexPage();
paramISuite.setAttribute("endExecution", Long.valueOf(System.currentTimeMillis()));
long l = ((Long)paramISuite.getAttribute("startExecution")).longValue();
generateConsolidatedPage();
generateCurrentRunPage(l, System.currentTimeMillis());
startReportingForPassed(this.passedTests);
startReportingForFailed(this.failedTests);
startReportingForSkipped(this.skippedTests);
if (Directory.generateExcelReports) {
ExcelReports.generateExcelReport(Directory.RUNDir + Directory.SEP + "(" + Directory.REPORTSDIRName + ") " + Directory.RUNName + this.runCount + ".xlsx", this.passedTests, this.failedTests, this.skippedTests);
}
if (Directory.generateConfigReports) {
ConfigurationListener.startConfigurationMethodsReporting(this.runCount);
}
if (Directory.recordSuiteExecution) {
try
{
this.recorder.stop();
}
catch (Throwable localThrowable) {}
}
}
catch (Exception localException)
{
throw new IllegalStateException(localException);
}
}
I suspect the issue comes from long l = ((Long)paramISuite.getAttribute("startExecution")).longValue(); because TestNG has some issues with listeners.
What you should do is installing a java decompiler in your IDE (for example http://jd.benow.ca/). Then, in debug mode, you'll be able to find where exactly is the issue.
You should try the latest TestNG version (6.9.12) too which is supposed to fix the previous listener issues.

While debugging manually and running the classes individually I found out that one of the class was throwing a nullpointer exception as there was a mismatch in the number of parameters passed.
