/**
* Forbid direct assembly wiring of a native method.
* On select platforms and when some conditions are met, BridJ connects the
* native code to Java using optimized assembly glues, which might not be as
* stable as using dyncall (BridJ's ffi
* library).
* In case of unexplained crash / bug, one should first try to set the
* BRIDJ_DIRECT=0 environment variable or set the bridj.direct=false Java
* property.
* If this solves the issue, a bug should be
* filed and this annotation can be used as a workaround to selectively
* disable raw calls for some methods.
