Summary

Fix for JDK-8334488 introduced a regression in JDK-24, there are several fixes, some of them currently under review, that will fix the introduced regression.

Problem

The fix for JDK-8334488 introduced a regression in JDK-24. Code like the following:

class Test {
    Test() {}

    Test(int a) {
        new InnerLocal() {}; //compilation fails here
        this();
    }
}

Is now incorrectly rejected by the javac compiler.

Solution

Since the aforementioned fix is correct, the fix will be left in place in 24, despite the regression. We have a fix in the work that will help remove the introduced regression is [1]. This second fix represents a major change to the compiler pipeline and for this reason it was deemed too risky to be integrated into JDK 23.

Specification

There are no changes to the specification.
