      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_25"
      Java(TM) SE Runtime Environment (build 1.8.0_25-b18)

      A DESCRIPTION OF THE PROBLEM :
      This is an upstream bug for:
      https://josm.openstreetmap.de/ticket/3290

      The attached small XML file contains a chinese character and the first gothic character (U+10330 : http://www.unicode.org/charts/PDF/U10330.pdf)
      When parsing this file using StaX, the attribute value containing the gothic character is corrupted: it contains also the chinese character from the previous attribute.
      See the console output:
      From XML chinese:[-16, -92, -83, -94]
      Expected chinese:[-16, -92, -83, -94]
      From XML gothic:[-16, -92, -83, -94, -16, -112, -116, -80]
      Expected gothic:[-16, -112, -116, -80]

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run attached program

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
