Summary: DateFormat.getDateTimeInstance() is very expensive, we
can cache it to improve performance
Product: Ant
Version: 1.8.2
Platform: PC
Status: NEW
Severity: normal

DateFormat.getDateTimeInstance() is very expensive, we can cache it to improve
performance. In the files:
./apache-ant-1.8.2/src/main/org/apache/tools/ant/taskdefs/Touch.java line:75
./apache-ant-1.8.2/src/main/org/apache/tools/ant/types/resources/selectors/Date.java
line: 141
DateFormat.getDateTimeInstance() is called in the critical section. We can
cache the result by adding a class member field. It can help reduce the work in
the critical section, and we only need to create the instance once.
This is similar to the Apache Bug 48778
