Description

In class org.apache.tapestry5.corelib.pages.PropertyDisplayBlocks the DateFormat used to format Dates is declared as:

private final DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.MEDIUM, locale);

Which is not correct because DateFormat is not thread safe and pages aren't pooled any more.
