java.lang.NoSuchMethodError after updating to 1.4.3-native-mt

[whyoleg]

After updating coroutines version from 1.4.2 to 1.4.3 (native-mt, not sure if it's matter) i have such errors on trying to run tests on K/JVM (IR):

'java.lang.Object kotlinx.coroutines.TimeoutKt.withTimeout-lwyi7ZQ(double, kotlin.jvm.functions.Function2, kotlin.coroutines.Continuation)'
java.lang.NoSuchMethodError: 'java.lang.Object kotlinx.coroutines.TimeoutKt.withTimeout-lwyi7ZQ(double, kotlin.jvm.functions.Function2, kotlin.coroutines.Continuation)'

on K/JS and K/Native it works well. on 1.4.2 everything works well.
project has dependencies on coroutines as well as ktor (which depends on coroutines 1.4.2-native-mt) and turbine.

Is the issue caused by changes in inline classes mangling scheme?
in 1.4.3 after upgrade to kotlin 1.4.30, coroutines uses new mangling schema from kotlin 1.4.30, while ktor uses old

Another possible cause of the issue is changed publication of MPP artifacts in 1.4.20

Is there workaround on consumer side possible?

Is the issue caused by changes in inline classes mangling scheme?

Indeed. The Kotlin version update (1.4.0 -> 1.4.30) affects users of experimental inline-classes.
So, 1.4.3 is basically incompatible with anything that relies on 1.4.2 and uses experimental inline-classes API.

But in that case, you had to get an experimentality warning: library authors shouldn't provide stable API that internally depends on experimental inline classes or other experimental API. If you didn't get the warning, I suggest filing an issue in the corresponding projecs.

This also affects (at least) kotlinx-coroutines-core-jvm, so perhaps the title of this issue should be made more general.
