If you look for a solution how to parse the whole given string in one and only one step then Java 8 offers this option (the pattern symbol V is not supported in SimpleDateFormat):

// V = timezone-id, HH instead of hh for 24-hour-clock, u for proleptic ISO-year
DateTimeFormatter dtf = 
  DateTimeFormatter.ofPattern("'DTSTART;TZID='VV:uuuuMMdd'T'HHmmss");
ZonedDateTime zdt = 
  ZonedDateTime.parse("DTSTART;TZID=America/Los_Angeles:20140423T120000", dtf);
Instant instant = zdt.toInstant();

// if you really need the old class java.util.Date
Date jdkDate = Date.from(instant);
