Not environment dependent.
Once you set the displayed TimeZones property of a Datebox you can empty it no more.
Internal list in component is set to null:
if (dtzones != null && dtzones.isEmpty()) dtzones = null;
Then its size is retrieved:
for (int i = 0; i < _dtzones.size(); i++) {
And that ends with a NullPointerException.
org.zkoss.zul.Datebox.setDisplayedTimeZones()
/**
* Sets a list of the time zones that will be displayed at the
* client and allow user to select.
* <p>If the {@link #getTimeZone()} is null,
* the first time zone in the list is assumed.
* @param dtzones a list of the time zones to display.
* If empty, it assumed to be null.
