Details about the known misuse from the MUBench dataset.
Description:
StringTokenizer.nextToken() is invoked without prior check of hasMoreTokens(). Test target method implements a lookup, which may be expected to throw if there is no matching element. However, this is not explicit.
Fix Description:
Violation Types:

String s = (String)fontDesc.get("FontBBox");
StringTokenizer tk = new StringTokenizer(s, " []\r\n\t\f");

for (int k = 0; k < idx; ++k)
ret = tk.nextToken();
return Integer.parseInt(ret);
