For non-invokedynamic JVMs, generates this code:
```java
if (__robo_data__ instanceof ThisClass) {
try {
return __robo_data__.$$robo$$originalMethod(params);
} (Throwable t) {
throw RobolectricInternals.cleanStackTrace(t);
}
}
```

Note that this method is only called by {@link OldClassInstrumentor}.
For non - invokedynamic JVMs generates this code : java if ( __robo_data__ instanceof ThisClass ) { try { return __robo_data__ . $$robo$$originalMethod ( params ) ; } ( Throwable t ) { throw RobolectricInternals . cleanStackTrace ( t ) ; } }
