/**
 * 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. * * @author ochafik */ @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.METHOD, ElementType.TYPE}) public @interface DisableDirect { }
