JAXB marshal if identation exceeds nested level 8

When calling JAXB marshal with pretty print it outputs:

The problem is when reaching indentation level 8 it restarts indentation.

The problem is in the:
IndentingUTF8XmlOutput.java

buggy function:
private void printIndent() throws IOException

{ write('\n'); int i = depth%8; write( indent8.buf, 0, i*unitLen ); i>>=3; // really i /= 8; for( ; i>0; i-- ) indent8.write(this); }

You can see that variable i is using remainder of division with 8.
After that i>>3 is already the remainder.
i >>= 3 (i = i >> 3) should be instead ... i = depth >> 3;

Other implementations does not exhibit such behavior.
