JRebel 7.0.0 Agent command line startup

With the release of JRebel 7, we have revised the agent file locations and startup configuration. You will need to edit your startup scripts!

Running the new JRebel Agent

The new JRebel Agent no longer works using -javaagent. This change affects users previously running with the Legacy Agent from a command line (as well as on a remote machine or container).

Here is how you should start the new JRebel Agent:

-agentpath:C:/JRebel/lib/jrebel64.dll

You need to replace the jrebel64.dll based on your operating system and JVM bitness:

  • jrebel64.dll — Using a 64-bit JVM on Windows.

  • jrebel32.dll — Using a 32-bit JVM on Windows.

  • libjrebel64.dylib — Using a 64-bit JVM on macOS.

  • libjrebel32.dylib — Using a 32-bit JVM on macOS.

  • libjrebel64.so — Using a 64-bit JVM on Linux.

  • libjrebel32.so — Using a 32-bit JVM on Linux.

Other operating systems and architectures

When using a non-x86 or non-x86-64 architecture, or different operating systems, follow the instructions here.
