This command:

/tellraw @s {"text":"a"}@

works, but it shouldn't. It outputs "a". Same with any other character at the end. But not two.

The reason is when reading a JSON text component, the position of the end cursor is one more than expected.

The issue lies on the method with remapped name class_9010.method_55376 (
ParserUtils.getPos), which has an extra +1. In versions 1.20.2 and below, the issue lies on class_2561.class_2562.method_10880 (Component.Serializer.getPos).

Confirmed not to happen for 24w14a.

This is fixed since 24w10a

Can confirm fixed in 24w10a. The command is not accepted anymore.
