A deeper look to DynHUD reveal that the guy behind use a Java RE 32bit in CLIENT MODE which is not optimized and not in server mode, they have an Oracle redistribution package and DO NOT use the OpenJDK. CLIENT mode has been dropped by Oracle...from 64Bit version of JRE and still appears in 32Bit windows only...
Anyway, you can simple remove the Java directory from C:\Program Files (x86)\Steam\steamapps\common\Automobilista\Plugins\DynHUD\
and replace it by the JRE provided in VDASH-EMU X86 for windows (32 bit version)
rename jre by Java
this has been tested here and works like a charm, as well.
Anyway, I still suggest to remove the DynHUD.dll and DynHUD directory from Automobilista plugins directory, all the info are already available in VDASH-EMU and this plugin is poorly optimized, it uses a dll as plugin to get telemetry/java RE 32bit non optimized even if you are on 64Bit Windows/and the bad directx9 dll hack to display telemetry info over the Automobilista screen a big waste of time and energy. They really need to drop java and use the native c++ to make the hud...
