[IR] Specify explicitly that classes from Java can be interpreted

In early prototypes of interpreter, it was easier to assume that
all classes from Java can be interpreted and fix something if not.
Check for Java declaration was done by checking that the package name is
starting with "java". But this is actually wrong and can lead to errors
when some code is declared in "java" something package, but is not from
Java stdlib.
