How do I start my Java program with more than one java agent?

There is a new project with the goal to support multiple Java agents. Currently it is limited to specific ones.

Agent Bond is a super agent, which wraps and dispatches on several other agents. That way, you only have to install a single agent within your JVM with a single set of configuration data (which contains multiple separate parts).

See https://github.com/fabric8io/agent-bond/blob/master/README.md for details

Adding to the above answers, if you are using ant and want to include <jvmargs /> with more than one jar to -javaagent to start the server, here's how I did it,

build.xml

<target name="blah">
...
    <jvmarg value="-javaagent:${jar1.path}" />
    <jvmarg value="-javaagent:${jar2.path}" />
...
</target>

It would appear you can do this by using multiple arguments. From the documentation:

On implementations with a command-line interface, an agent is started by adding this option to the command-line:

-javaagent:jarpath[=options] 

jarpath is the path to the agent JAR file. options is the agent options. This switch may be used multiple times on the same command-line, thus creating multiple agents. More than one agent may use the same jarpath. An agent JAR file must conform to the JAR file specification.

(my emphasis)

How about two javaagent parameters?

java -javaagent:agentA.jar -javaagent:agentB.jar MyJavaProgram
