For codegen the compile exception is like:
```
No applicable constructor/method found for actual parameters
"org.apache.spark.unsafe.types.UTF8String"; candidates are: "public void
org.apache.spark.sql.catalyst.expressions.TestBean.setX(int)"
```
I'm not sure if we want to exactly match this kind of exception message
from interpreted execution. Might be a little overkill to do that by looking
methods with same name. So currently I only test interpreted execution.
