NoClassDefFoundError: com.sun.management.OperatingSystemMXBean at ...Performance.getHealthCheck(Performance.java:127)

Question

The method net.sourceforge.plantuml.api.Performance.getHealthCheck(), in Line 127 uses the  com.sun.management.OperatingSystemMXBean class, that isn't included in all jvm.  A previous test like:

 

final Class cl = Class.forName("com.sun.management.OperatingSystemMXBean");

if (cl == null) {

   Log.info("Cannot load com.sun.management.OperatingSystemMXBean");

   jvmCpuTime = -1;

} else if (...)

 

could prevent the code from breaking up.

Answer 1

We have made a beta that should correct this :

Could you test it and tell us if it's fine for you ?

Thanks,

Sorry for the delayed answer: vacations and a different project have kept me busy in other fronts. I'll give it a try as soon as I can.
