<h1 id="-djavacompiler">-Djava.compiler</h1>
<p>This Oracle HotSpot property is used for loading a JIT compiler from a named, native library. This option can be used on the command line to specify the JIT compiler for the OpenJ9 VM.</p>
<h2 id="syntax">Syntax</h2>
<pre><code>    -Djava.compiler=j9jit29
</code></pre>
<!-- OLD: 
## Explanation

Enable JIT compilation by setting to `j9jit<vm_version>`, where `<vm_version>` is the version of the J9 virtual machine. Use only digits, for example "29" for VM version 2.9. Check the output of the `java -version` command to confirm your VM level. (Equivalent to `–Xjit`).-->
