OS: Windows 10
JRE 1.8.0_202
I'm having trouble getting output from the Java Usage Tracker described at https://docs.oracle.com/javacomponents/usage-tracker/overview/toc.htm
I am using the example properties file describe in the document. The only change is that I removed the leading dot from the output filename ".java_usagetracker", since Windows does not want to create a file with a leading dot.
My test is a simple HelloWorld class that does execute and print the output string:
public class HelloWorld {
public static void main(String[] args)
{
System.out.print("Hello World");
}
}
The usagetracker.properties file is in C:\Program Files\Java\conf with the aim of monitoring all installed JREs - my workstation has jre1.8.0_192 and jre1.8.0_202 installed. Looking at the timestamps in oracle_jre_usage, it appears that the 202 update is the JVM that runs.
The output file specified in my properties file never gets created. Can anyone suggest what I'm missing or suggest a different test I can run? Thanks.
