Summary: org.tm4j.topicmap.cmd.Merge crashes

Initial Comment:
call "java org.tm4j.topicmap.cmd.Merge -c test.xtm", where "test.xtm" is this file:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE topicMap PUBLIC "-//TopicMaps.Org//DTD XML Topic Map (XTM) 1.0//EN"
                          "http://www.topicmaps.org/xtm/1.0/xtm1.dtd">
<topicMap id="x1nnj36ct9-0"
  xmlns="http://www.topicmaps.org/xtm/1.0/" xmlns:xlink="http://www.w3.org/1999/xlink">
  <topic id="id129">
    <instanceOf>
      <topicRef xlink:href="#x1nnj36d5b-7"/>
    </instanceOf>
  </topic>
  <topic id="x1nnj36d5b-7">
    <subjectIdentity>
      <subjectIndicatorRef xlink:href="http://psi.somewhere/#something"/>
    </subjectIdentity>
  </topic>
</topicMap>
