LOOKAHEAD_DEPTH

protected static final int LOOKAHEAD_DEPTH

Depth of at least 3 is needed for J9 javacores, as parsing a section from the start will yield three tokens: SECTION, header information token, first TAG of section (note that NULL lines are ignored by the scanner). Adjust as necessary for deeper analysis.
