Functional expression can be folded
Reports method references or lambda expressions that point to a method of their own functional interface type and hence can be replaced with their qualifiers removing unnecessary object allocation.
Example:
SwingUtilities.invokeLater(r::run);
SwingUtilities.invokeAndWait(() -> r.run());
After the quick-fix is applied:
SwingUtilities.invokeLater(r);
SwingUtilities.invokeAndWait(r);
This inspection reports only if the language level of the project or module is 8 or higher.
