Normally, 'DefaultErrorMessages' extensions should only be loaded
from the main compiler JAR. However, in the in-process JPS build,
there are two versions of the compiler classes in the process, and
'ClassLoader's there are not fully isolated.
'ServiceManager' loads extensions from both 'META-INF' locations. If
the JPS plugin bundles newer compiler components, newly appeared
'DefaultErrorMessages' extensions will be loaded from the JPS (parent)
'ClassLoader', causing an exception.
Such a problem appeared with 'DefaultErrorMessagesWasm':

java.util.ServiceConfigurationError:
org.jetbrains.kotlin.diagnostics.rendering.DefaultErrorMessages$Extension: org.jetbrains.kotlin.wasm.resolve.diagnostics.DefaultErrorMessagesWasm not a subtype
