[JIT] Jit compiler panic
Yet another kind of panic:
thread 'main' panicked at 'assertion failed: `(left != right)`
left: `String`,
right: `String`', crates/dataflow-jit/src/ir/validate.rs:970:17

It's because you're trying to perform logical or on strings which doesn't exist, you probably want to call the @dbsp.str.concat_clone() and @dbsp.str.concat() functions
Here is am improved JSON program, which causes a different panic, similar to #386
