RFR: 8297974: ClassCastException in com.sun.tools.javac.comp.AttrRecover.doRecovery

[Jan Lahoda]

Considering code like:

class RecoveryTest {

    interface I {
        int convert(int i);
    }

    void t(I f, String e) {
        t(param -> param); //a parameter missing here
    }

}


This is clearly wrong (the invocation of `t` is missing a parameter). But, running this crashes the compiler in addition to reporting the error:

$ javac -XDdev RecoveryTest.java
