first jstat command in sun/tools/jstat/jstatLineCounts1.sh is failing

[Note this CR also applies to jstatLineCounts2.sh, jstatLineCounts3.sh and jstatLineCounts4.sh]

There are two jstat command in these scripts:

jstat -gcutil -h 10 0 250 11 2>&1 | awk -f ${TESTSRC}/lineCounts1.awk
jstat -J-XX:+UseParallelGC -gcutil -h 10 0 250 11 2>&1 | awk -f ${TESTSRC}/lineCounts1.awk

The first one is now failing the checking done by lineCounts1.awk. However, the failure has gone undetected due to the second jstat command that was added by JDK-8245129, which causes the failure of the 1st command to go undetected. JDK-8268484 has been filed for this failure detection issue. The real issue with the CR is that the output of the first command now has all 0's:
