 Review comment:
   Undoing this diff results in the following failure:
   ```
   JavaBeanSchemaTest.java:158: error: reference to assertEquals is ambiguous
       assertEquals((byte) 1, nestedRow.getByte("aByte"));
       ^
     both method assertEquals(long,long) in Assert and method 
assertEquals(Object,Object) in Assert match
   ```
   
   @amaliuja Your suggestion results in the following failure:
   ```
   JavaBeanSchemaTest.java:158: error: incompatible types: int cannot be 
converted to Byte
       assertEquals((Byte) 1, (Byte) nestedRow.getByte("aByte"));
   ```
   
   @akedin Your suggestion results in the following failure:
   ```
       assertEquals(Byte.valueOf(1), nestedRow.getByte("aByte"));
                        ^
       method Byte.valueOf(byte) is not applicable
         (argument mismatch; possible lossy conversion from int to byte)
       method Byte.valueOf(String) is not applicable
         (argument mismatch; int cannot be converted to String)
   ```
   Using `assertTrue` is incorrect because it does not print the values on 
failure. I'm happy to change the syntax, but none of these options work.
