Class InstrumentationRuntimeFactory

java.lang.Object

org.broadleafcommerce.common.extensibility.InstrumentationRuntimeFactory

Deprecated.

Because of classloader differences, this approach is not reliable for some containers. Use the javaagent jvm argument instead to set instrumentation.

@Deprecated
public class InstrumentationRuntimeFactory
extends java.lang.Object

This class is based on the OpenJPA's org.apache.openjpa.enhance.InstrumentationFactory. It essentially does its best to install an instrumentation agent. The preferred or prescribed way to install an instrumentation agent is to add the agent as an argument on the command line when starting the JVM. This class attempts to do the same thing after the JVM has already started. Unfortunately, this is the only way we know of to attach an agent to the JVM except by adding a "javaagent:..." flag on the command line.

Method Detail

agentmain

public static void agentmain(java.lang.String agentArgs,
                             java.lang.instrument.Instrumentation instrumentation)

Deprecated.

This method is called by the JVM to set the instrumentation. We can't synchronize this because it will cause a deadlock with the thread calling the getInstrumentation() method when the instrumentation is installed.

Parameters:

agentArgs -

instrumentation -

getInstrumentation

public static java.lang.instrument.Instrumentation getInstrumentation()

Deprecated.

This method returns the Instrumentation object provided by the JVM. If the Instrumentation object is null, it does its best to add an instrumentation agent to the JVM and then the instrumentation object.

Returns:

Instrumentation
