One of our customers is trying to generate XML report using below mentioned command.

java -cp ".\common-9.1.0-SNAPSHOT.jar;.\flightrecorder-9.1.0-SNAPSHOT.jar;.\flightrecorder.rules-9.1.0-SNAPSHOT.jar;.\flightrecorder.rules.jdk-9.1.0-SNAPSHOT.jar;.\lz4-java_1.8.0.jar;.\org.owasp.encoder_1.2.3.jar" org.openjdk.jmc.flightrecorder.rules.report.JfrRulesReport JFRFileName.jfr -verbose -format xml > XmlFileName.xml

The report is not generated and the console is showing NullPointerException as below:

Caused by: java.lang.NullPointerException: Cannot invoke "org.openjdk.jmc.common.item.IMemberAccessor.getMember(Object)" because "a" is null
