Thanks. Do you recall what you were doing at the time?

Thanks. Do you recall what you were doing at the time?

Waterfalls and EQ. It has happened twice now.

 

[John Mulcahy]

OK, if you notice any specific sequence of actions that triggers it please post them here.

java.lang.NullPointerException i gpt this error also....
It happend after doing a measurement, 20-500 hz 512k & 4 repetitions

i used the umik-1 and a steinberg ur28 sound card on windows 10

I noticed that my soundcard was at 44.1khz while the java driver in rew was at 48khz

I did the measurement at beta 26, so i updated to beta 27 & reboot windows
but i keep getting this error java.lang.NullPointerException
when i calibrate the sound in preferences all works o,k,m but when i go to measurement
and click on check levels i get the error every time

when i go to measurement and click on check levels i get the error every time

The stack trace is truncated but I think I have worked out what could cause that and fixed it for the next build.

 

[Davo013]

Okay John! Great!
Keep up the good work!

I updated windows & java, but that didn’t help at all..
Then I searched the whole internet about java.lang.NullPointerException but I couldn’t find something useful...
But i have zero experience with java lol

The weird thing is that with beta26 I never had that problem, and I was still on beta 26 and i didn’t do any updates at all...
I always disable auto updates..

But after updating windows, java & rew and checking all settings I managed to find a little work-around to check the levels for making measurements...

I used rew’s external tone generator & spl meter to set the correct spl level.

Hopefully I might be useful to someone who uses the uses the umik-1 or uses java

...

An NPE is a common error. It happens when the code tries to access memory address 0, an uninitialized pointer.

If the cause it what I think it is a very specific timing of events is required to trigger it, I don't think it is a widespread occurrence.

 

[Davo013]

Well John thnx for the update, i just updated to beta 28 and the problem still exists.... sigh

i really dunno what's wrong... or how to solve it...
When i check the levels i hear no sound, and when i click outside the measurement window i get the java erro

 

[John Mulcahy]

Per our separate conversation, looks like I have now found the source of the problem you are seeing and it has been fixed for the next build.

 

[Davo013]

Awesome John!
You nailed that buggin’ bug!
Cheers!

It's an old thread, but I am finding similar error on 2 different computers (an 11th gen i5 and an old laptop, both running Windows 10).
The error occurs when importing the response file after importing the stimulus. If the message is closed the procces gets stuck at "calculating frequency response...". Upon closing the Import sweep windows REW seems to keep working fine, but no measurement is loaded.

In both computers the error message is identical:

A very old thread
