Non-thread-safe 'static' field access
Reports access to static
fields that are of a non-thread-safe type.
When a static
field is accessed from an instance method or a non-synchronized block, multiple threads can access that field. This can lead to unspecified side effects, like exceptions and incorrect results.
Example:
class Sample {
private static final SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
String method() {
return df.format("");
}
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
AccessToNonThreadSafeStaticField
You can specify which types should be considered not thread-safe. Only fields with these exact types or initialized with these exact types are reported, because there may exist thread-safe subclasses of these types.
Here you can find the description of settings available for the Non-thread-safe 'static' field access inspection, and the reference of their default values.
