java.lang.management not available on Android

@igr, it would appear as if the newest Android Studio (or one of its libraries) was not too fond of the use of java.lang.management.ManagementFactory in jodd.util.SystemInfo

jodd-util/src/main/java/jodd/util/SystemInfo.java

Line 495 in 8d7398b

    
           return Long.parseLong(ManagementFactory.getRuntimeMXBean().getName().split("@")[0]);

The error message is

Missing class java.lang.management.ManagementFactory (referenced from: long jodd.util.SystemInfo.getCurrentPID())
Missing class java.lang.management.RuntimeMXBean (referenced from: long jodd.util.SystemInfo.getCurrentPID())

That seems to be a general issue with that package on Android -> https://stackoverflow.com/a/19595885 and Kotlin/kotlinx.coroutines#959

It's possible to "skip" that error, so it's not a complete show-stopper. Rather a heads-up :)

Maybe I can just remove that method, as on Java9 there is a new way anyway: long pid = ProcessHandle.current().pid();

6.2.1. released:)
