Unable to run on Mac using java 1.8.0_202

[somerboy]

I recently upgraded computers and Java got upgraded from 1.5 to 1.8. When I run the command "java -Xms512M -Xmx1G -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -jar pega-tracerviewer-3.0.jar" I get a null pointer exception immediately.

I had similar issue. I fixed by updating the line 48 in the pega-tracerviewer unix script file to: # Add default JVM options here. You can also use JAVA_OPTS and PEGA_TRACERVIEWER_OPTS to pass JVM options to this script. DEFAULT_JVM_OPTS='"-Duser.dir=$APP_HOME" "-Dfile.encoding=UTF-8" "-Xms512M" "-Xmx1G" "-XX:+UseG1GC" "-XX:+UseConcMarkSweepGC" "-XX:+IgnoreUnrecognizedVMOptions"'

To fix: Unrecognized VM option 'UseParNewGC' https://stackoverflow.com/questions/49962437/unrecognized-vm-option-useparnewgc-error-could-not-create-the-java-virtual

To fix: Unrecognized VM option 'UseConcMarkSweepGC' https://stackoverflow.com/questions/65546614/unrecognized-vm-option-useconcmarksweepgc-when-running-sample-project

With the above code change, TracerViewer is running fine for me in Mac
