Can't bind to engine

import org.junit.Test
import javax.script.ScriptEngineManager
import kotlin.test.assertEquals

class ScriptTest {

@Test
fun testSimpleEval() {
val engine = ScriptEngineManager().getEngineByExtension("kts")!!
val res = engine.eval("2+4")
assertEquals(6,res)
}

@Test
fun testSimpleBinding() {
val engine = ScriptEngineManager().getEngineByExtension("kts")!!
engine.put("hello","world")
val res = engine.eval("hello")
assertEquals("world",res)
}
}

I've got

javax.script.ScriptException: Unresolved reference: hello
at org.jetbrains.kotlin.cli.common.repl.KotlinJsr223JvmScriptEngineBase.compileAndEval(KotlinJsr223JvmScriptEngineBase.kt:65)
at org.jetbrains.kotlin.cli.common.repl.KotlinJsr223JvmScriptEngineBase.eval(KotlinJsr223JvmScriptEngineBase.kt:31)

Start by running the shown ScriptTest reproduction with ScriptEngineManager.getEngineByExtension("kts"). Focus on the testSimpleBinding path using engine.put("hello", "world") followed by engine.eval("hello"); done means the evaluation resolves hello and the assertEquals("world", res) test passes.
