Thrift 3486 - Java generated `getFieldValue` is incompatible with
`setFieldValue` for binary values.
For binary fields, the compiler generates Java getter/setter methods for
primitive byte arrays (`byte[]`) as well as `java.nio.ByteBuffer` objects.
However, `setFieldValue` only accepts a `ByteBuffer`, and throws a
`ClassCastException` if a `byte[]` is passed as an argument. To further confuse
things, `getFieldValue` returns a `byte[]`. By allowing either a `ByteBuffer`
or a `byte[]` as input, `setFieldValue` could exhibit less confusing behavior
for end users.
These changes add an `instanceof` check for binary fields in the generated
`setFieldValue()` method so that it accepts either a `byte[]` or a
`ByteBuffer`. There is also an update to the Java library's test suite to test
for this functionality.

Added an 'instanceof' check for binary fields in the generated
setFieldValue() method so that it accepts either a byte[] or a ByteBuffer. The
compiler generates getter/setter methods for both types, but previously
setFieldValue only would accept a ByteBuffer. To further confuse things,
getFieldValue returns a byte[]. By allowing either a ByteBuffer or a byte[] as
input, setFieldValue exhibits less confusing behavior for end users.
