Hi Chuck,
could you elaborate more on the shared formatters thing?
Don't Do Stupid Things :-) Which boils down to don't share objects that are not thread-safe, or writable data, at the global level unless you have appropriate protection. Global being either static members or instance variables on your application. Shared, non-thread safe formatters are a common mistake.
we inherited a project that has random (but infrequent) lockups and I found that in the Application.java
first there is an instance variable
private NSNumberFormatter millionsFormatter;
then a lazy initialization in the accessor method:
public NSNumberFormatter millionsFormatter() {
if (millionsFormatter ==null) {
millionsFormatter = new NSNumberFormatter();
millionsFormatter.setPattern("###,##0.00");
millionsFormatter.setDecimalSeparator(",");
millionsFormatter.setThousandSeparator(".");
}
return millionsFormatter;
}
Could this approach be one of the causes of the lockups? The app runs in multithreaded mode and there are tons of components with WOStrings bound to this formatter...
Thanks,
Matteo
