     Approach #1: Snip out the entire inside of scanXan() and
paste it in place of the method call, renaming foo to args or
args to foo (or getting rid of both).

     Approach #2: As above, but consolidate the nested try/catch
structure from

	try {
	    ...
	    try {
	        ...
	    }
	    finally {
	        ...
	    }
	} catch (Exception e) {
	    ...
	}

to the simpler

	try {
	    ...
	} catch (Exception e) {
	    ...
	}
	finally {
	    ...
	}
