Gary Gregory updated LOG4J2-1553:
---------------------------------
Description:
The class {{AbstractManager}} should implement {{java.lang.AutoCloseable}}.
A manager holds on to resources that must be cleaned up. Typically these
resources are allocated on instance creation and freed by calling the manager's
{{release()}} method.
There are several benefits to this change:
- Make it obvious and formal that this kind of object must be properly managed.
- A reader or cloner of the code will know that there is a pattern to follow.
- This will make our tests cleaner, smaller and hopefully less error-prone.
Our current unit test code follows this pattern:
{code:java}
SomeManager mgr = new SomeManager(lots, of, params);
try {
// test code
} finally {
mgr.close();
}
{code}
Sometimes, we also have:
{code:java}
SomeManager mgr = new SomeManager(lots, of, params);
try {
// test code
} finally {
if (mgr != null) {
mgr.close();
}
}
{code}
After the proposed change, our test code can look like this:
{code:java}
try (SomeManager mgr = new SomeManager(lots, of, params)) {
// test code
}
{code}

There are several benefits to this change:
- Make it obvious and formal that this kind of object must be properly managed.
- A reader or cloner of the code will know that there is a pattern here.
- Cleans up our unit tests which handle managers explicitly.
This pattern is used in many of our unit tests.
