I'm meaning it. It sets the end pointer to line no. somewhere beyond nirwana so the test will fail until the first pattern is matched.

Sorry for the delayed response.

The command is not retruning exact value. I only has 48 null pointer exception so it should retrun around 1200 lines.

Code:
$awk -v P1="ERROR OCCURRED :" -v P2="java.lang.NullPointerException" \
>         '$0 ~ P1        {PR=1; EP=1E99}
>          $0 ~ P2 && PR  {EP=NR+25}
>          NR > EP        {PR=0}
>          PR
>         ' trace.log | wc -l
2112687
$wc -l trace.log
2207494 trace.log
$grep -c "java.lang.NullPointerException" trace.log
48
$
