General JVM options can be passed to the Minecraft Server invocation by passing a `JVM_OPTS`
environment variable. The JVM requires `-XX` options to precede `-X` options, so those can be declared in `JVM_XX_OPTS`. Both variables are space-delimited, raw JVM arguments.
```
-e JVM_OPTS="-someJVMOption someJVMOptionValue"
```
For some cases, if e.g. after removing mods, it could be necessary to startup minecraft with an additional `-D` parameter like `-Dfml.queryResult=confirm`. To address this you can use the environment variable `JVM_DD_OPTS`, which builds the params from a given list of values separated by space, but without the `-D` prefix. To make things running under systems (e.g. Plesk), which doesn't allow `=` inside values, a `:` (colon) could be used instead. The upper example would look like this:
`JVM_DD_OPTS=fml.queryResult:confirm`, and will be converted to `-Dfml.queryResult=confirm`.
