JRebel: Attaching the agent at runtime?

I can successfully attach many other agents at runtime using ByteBuddyAgent (byte-buddy-agent), but for some reason JRebel fails.

Caused by: com.sun.tools.attach.AgentLoadException: Failed to load agent library: _Agent_OnAttach@12 is not available in C:\JRebel\lib\jrebel64.dll
    at jdk.attach/sun.tools.attach.VirtualMachineImpl.execute(VirtualMachineImpl.java:126)
Caused by: com.sun.tools.attach.AgentLoadException: Failed to load agent library: _Agent_OnAttach@12 is not available in C:\JRebel\lib\jrebel64.dll

    at jdk.attach/sun.tools.attach.HotSpotVirtualMachine.loadAgentLibrary(HotSpotVirtualMachine.java:94)
    at jdk.attach/sun.tools.attach.HotSpotVirtualMachine.loadAgentPath(HotSpotVirtualMachine.java:128)
    ... 11 more

Is there any way I can get around this? Because I'd like to attach JRebel only after certain initialization steps occur in my program.

The JRebel agent cannot be attached at runtime as the tool itself has to complete many initialization procedures.

Can I ask why you need the JRebel agent needs to be attached after certain initialization steps?

I assume that Byte Buddy loads classes that JRebel expects to be unloaded. This might not be possible. Get in touch with JRebel to see if they can extract a more helpful error message to possibly resolve this.
