> {{getLastModifiedTime()}} of {{Function.java}} assumes that if the UDF is not a BUILTIN and if the location is not null, it is a non-empty string. However, we may have UDFs with an empty location if they are in the install location and loaded at init time.
> We should also add a non empty check for the location in the if condition.
