Generating static class initializer using javapoet

Question

Is it possible to generate static initializer using javapoet? See an example of what I'm trying to generate below:

class Foo {
    static int one = 1;
    static int two = 2;
    static int sum;

    static {
        sum = one + two;
    }
}

I tried adding static initializer as a constructor with static modifier:

TypeSpec.classBuilder("Foo")
    .addField(FieldSpec.builder(int.class, "one", Modifier.STATIC).initializer("1").build())
    .addField(FieldSpec.builder(int.class, "two", Modifier.STATIC).initializer("2").build())
    .addField(int.class, "sum", Modifier.STATIC)
    .addMethod(MethodSpec.constructorBuilder()
        .addModifier(Modifier.STATIC)
        .addCode("sum = one + two;")
        .build())
    .build();

But this produces static Foo() { ... } instead of static {...}, which is incorrect syntax.

Is there a way to do it?

This cannot be done with version 1.0, the latest at time of writing.

However, there is a pull request to address this (https://github.com/square/javapoet/pull/257) which will hopefully be merged before the next release (most likely version 1.1).
