Conditional expression with identical branches

Reports conditional expressions with identical then and else branches.

Such expressions almost certainly indicate bugs. The inspection provides a fix that collapses conditional expressions.

Example:

int y = x == 10 ? 4 : 4;

After the quick-fix is applied:

int y = 4;
