System Console Oscilloscope function does not aleays work with NIOS

I am doing data acquisition using the ADC in the MAX 10. I am trying to us the oscilloscope function of the System Console to monitor the ADC inputs.  

When I am using it without the NIOS it works fine. When I install the NIOS Processor and call System Console from Eclipse it will work occasionally but usually I get the following error messages:  

 

master_write_32: java.lang.NullPointerException 

 

while executing 

"master_write_32 $sequencer_service 0x0 1 

(procedure "::adc_toolkit::trigger_sample_trace" line 39) 

invoked from within 

"::adc_toolkit::trigger_sample_trace $channel_number $sample_size" 

(procedure "::adc_toolkit::trigger_sample" line 3) 

invoked from within 

"::adc_toolkit::trigger_sample $channel_number $sample_size 

(procedure "::adc_toolkit::scope_test" line 28) 

invoked from within 

"::adc_toolkit::scope_test" 

("uplevel" body line 1) 

invoked from within 

"uplevel 1 $command_string 

(procedure "::adc_toolkit::debug_timer_run" line 7) 

invoked from within 

"::adc_toolkit::debug_timer_run ::adc_toolkit::scope_test {scope test}" 

("after" script) 

 

Any idea why it sometimes works and sometimes fails? 

I am using Quartus Version 15
