Statement can be replaced with 'assert' or 'Objects.requireNonNull'
Reports if statements that throw only java.lang.Throwable from a then branch and do not have an else branch. Such statements can be converted to more compact assert statements.
The inspection also reports Guava's Preconditions.checkNotNull(). They can be replaced with a Objects.requireNonNull() call for which a library may not be needed.
Example:
if (x == 2) throw new RuntimeException("fail");
if (y == null) throw new AssertionError();
Preconditions.checkNotNull(z, "z");
After the quick-fix is applied:
assert x != 2 : "fail";
Objects.requireNonNull(y);
Objects.requireNonNull(z, "z");
By default, this inspection provides a quick-fix in the editor without code highlighting.
