'ThreadLocal' field not declared 'static final'
Reports fields of type java.lang.ThreadLocal that are not declared static final.
In the most common case, a java.lang.ThreadLocal instance associates state with a thread. A non-static non-final java.lang.ThreadLocal field associates state with an instance-thread combination. This is usually unnecessary and quite often is a bug that can cause memory leaks and incorrect behavior.
A quick-fix is suggested to make the field static final.
Example:
private ThreadLocal tl = ThreadLocal.withInitial(() -> Boolean.TRUE);
