Move statements before super(..) in Java constructor #5397

[rkampani]

What's changed?

Relates to #5397
Jep 513 calls for allowing statements before the call to super() in Java constructors, allowing for simple assignments and validations before doing expensive construction.

Java version >= 25
(Also double check Jep 513 lands in Java 25)

Before Applying Recipe

class A {
    public A(String bar) {
        super();
        if(bar.equals("test"))
            throw new RuntimeException();
    }
}

After Applying Recipe

class A {
    public A(String bar) {
        if(bar.equals("test"))
            throw new RuntimeException();
        super();
    }
}

Great to see already, but apologies for the mix up; this should have gone into rewrite-migrate-java along with the other Java migration recipes. Would you mind targeting that one instead?

[rkampani]

Done — closing this PR as it was targeted to the rewrite-migrate-java repo, as requested.

Thanks! And sorry again for the confusion; we'd logged the issue as to not forget, but didn't expect your enthusiasm to pick it up already. :)
