Add method java.lang.String.getBytes(byte[], int, byte)

Add method java.lang.String.getBytes(byte[], int, byte) to MJI model class for java.lang.String

This also fixes:

[junit] java.lang.NoSuchMethodError: java.lang.String.getBytes([BIB)V
[junit] at java.lang.AbstractStringBuilder.putStringAt(AbstractStringBuilder.java:1641)
