-Xint

As described in the Oracle "Non-Standard Options" documentation, this VM option runs an application in interpreted-only mode. For compatibility, this option is also supported by the Eclipse OpenJ9™ VM.

Syntax

    -Xint

Explanation

If you use this option, the OpenJ9 VM uses only the interpreter, disabling the OpenJ9 just-in-time (JIT) and ahead-of-time (AOT) compilers. By default, both these compilers are enabled, although the AOT compiler is not used by the VM unless shared classes are also enabled.
