Description

The java launcher used with Ja.NET SE is the same one provided with Harmony.  It is capable of launching applications both on .NET as well as the Harmony VM, and by default, will start up applications to run on the .NET runtime. If you'd prefer the launcher to use the Harmony VM, then use the -vmdir:drlvm option on the command line, and the launcher will start up the Harmony VM, instead of .NET.

We have included the options that are relevant to launching applications on .NET below for your reference. Not all Java launcher options apply to starting up applications on .NET, and in those cases, we silently ignore them and continue running the application. For a complete list of Harmony launcher options, reference the online Harmony documentation.
