NullPointerException on JRBaseFiller

dthnam90 · October 28, 2014

Hi all,

The report run well on version 3.7.4 but it failed on 5.0.1 with the Null Pointer Exception on JRBaseFiller (line 2575). If anyone have had this error before, please help to share your ideas ?

Thanks,

Nam

Thanks nthapa for the suggestion, but it does not help. I have tried to upgrade to latest version (5.6.1) and still got the same error.

Thats interesting because I looked at the code and dont think that exception should be there, are you getting different exception may be?

I still got NullPointerException, but it happen in DelayedFillActions.java (line 525). I noticed that we have another exception: java.lang.InterruptedException. Below is the full log:
