Flags that control the behavior of our virtual machine.

Typically these are properties that can be set from the command line (and thus are NOT final). All final properties should be declared in Configuration

Field Detail

writingBootImage

public static boolean writingBootImage

use classes for boot image generation? (see BootImageWriter)

runningTool

public static boolean runningTool

use classes for generic java programming?

runningVM

public static boolean runningVM

use classes for running actual VM?

writingImage

public static boolean writingImage

are we in the boot-image-writing portion of boot-image-creation

fullyBooted

public static boolean fullyBooted

is the running VM fully booted? Set by VM.boot when the VM is fully booted.

safeToAllocateJavaThread

public static boolean safeToAllocateJavaThread

Is it safe to create a java.lang.Thread now? Set by VM.boot at the appropriate time.

verboseBoot

public static int verboseBoot

The following is set on by -X:verboseBoot= command line argument. When true, it generates messages to the sysWrite stream summarizing progress during the execution of VM.boot

verboseSignalHandling

public static boolean verboseSignalHandling

The following is set on by -X:verboseSignalHandling command line argument. When true, it generates messages to the sysWrite stream when a hardware exception is delivered to a thread.

verboseClassLoading

public static boolean verboseClassLoading

The following is set on by -verbose:class command line argument. When true, it generates messages to the sysWrite stream summarizing class loading activities

verboseJNI

public static boolean verboseJNI

The following is set on by -verbose:jni command line argument. When true, it generates messages to the sysWrite stream summarizing JNI activities
