This pattern of code is duplicated 3 times and should be consolidated

http://hg.openjdk.java.net/jdk/jdk/file/8c73d2a46ba9/src/hotspot/share/classfile/classLoader.cpp#l567

  Thread* THREAD = Thread::current();
  int len = (int)strlen(class_path);
  int end = 0;

  // Iterate over class path entries
  for (int start = 0; start < len; start = end) {
    while (class_path[end] && class_path[end] != os::path_separator()[0]) {
      end++;
    }
    EXCEPTION_MARK;
    ResourceMark rm(THREAD);
    char* path = NEW_RESOURCE_ARRAY(char, end - start + 1);
    strncpy(path, &class_path[start], end - start);
    path[end - start] = '\0';
