Please not that this does *not* work if the path does contain spaces,
so we cannot offer this as a general solution.

> set.default.JAVA_HOME=
> set.MERLIN_HOME=%DAISY_HOME%/repository-server/merlin
> set.WRAPPER_HOME=%DAISY_HOME%/wrapper
>
> # Java Application
> wrapper.java.command=%JAVA_HOME%/bin/java.exe
>
> And it's working fine including /bin suffix

but not if %JAVA_HOME% is not set as environment variable
