played around with JNIPort, which I downloaded from VAStGoodies and imported into my VASt 8.6.2. Unfortunately the provided sample code fails with a "Primitive failed" in JNIPortJNIInterface>>#JNI_CreateJavaVM:with:with:
'Primitive failed calling ''c:\Program Files (x86)\Java\jre1.8.0_202\bin\client\jvm.dll'':JNI_CreateJavaVM from PlatformFunction>>#callWith:with:with: due to Floating point underflow'
