[java] UnusedAssignment - false-positive boolean flag for execution and reset in finally

[Wolf2323]

Affects PMD Version: 7.1.0

Rule: UnusedAssignment

Description:
a flag set in a method, and directly reset after executing some code causes a UnusedAssignment since PMD 7. In PMD 6 this was no issue

Code Sample demonstrating the issue:

	@Override
	public void run(@NotNull final Runnable runnable) {
		if (entered || conflict) {
			return;
		}
		try {
			entered = true;
			runnable.run();
		} finally {
			entered = false;
		}
	}

Expected outcome:
This should be fine as the runnable can get the set flag and can access the method again.
