Hello,
I saw simillar issue #196 where it was fixed, however, there is a simillar issue, where other symbols aren't covered with provided solution in #196.

Used Kotlin and JDK 17, and this dependencies:

    implementation("org.infinispan.protostream:protostream:5.0.12.Final")
    compileOnly("org.infinispan.protostream:protostream-processor:5.0.12.Final")
    kapt("org.infinispan.protostream:protostream-processor:5.0.12.Final")

For example.
SImpleEntity

import org.infinispan.protostream.annotations.ProtoField

data class SimpleEntity(
    @get:ProtoField(number = 1) var name: String? = null,
    @get:ProtoField(number = 2) var message: String? = null
)

SimpleEntitySchema

@ProtoSchema(includeClasses = [SimpleEntity::class], schemaPackageName = "proto")
interface SimpleEntitySchema : GeneratedSchema

Generated SimpleEntitySchemaImpl.java

public class SimpleEntitySchemaImpl implements proto.SimpleEntitySchema {

   private static final String PROTO_SCHEMA = """
// File name: SimpleEntitySchema.proto
// Generated from : SimpleEntitySchema.proto
syntax = "proto2";
package proto;

I am using Embedded Infinispan cache with Quarkus, if it does matter.

@ApplicationScoped
class EmbeddedCache {

    private val cacheManager = DefaultCacheManager(
        GlobalConfigurationBuilder().clusteredDefault().serialization().addContextInitializer(
            SimpleEntitySchemaImpl()
        ).build()
    ).apply {
        defineConfiguration(
            "embedded-cache", ConfigurationBuilder().encoding().mediaType(MediaType.APPLICATION_PROTOSTREAM).build()
        )
    }

    private val keyCounter = AtomicLong(1)

    private val cache: Cache<Long, SimpleEntity> = cacheManager.getCache("embedded-cache")

    fun put(entity: SimpleEntity): String {
        val generatedKey = keyCounter.getAndIncrement()
        cache.put(generatedKey, entity)
        return "Successfully created new entity: $generatedKey | ${entity.name}"
    }

    fun get(key: Long): SimpleEntity? = cache[key]

    fun getAllEntities(): Map<Long, SimpleEntity> = cache

    fun updateEntity(key: Long, entity: SimpleEntity): String {
        if (cache[key] != null) {
            cache.put(key, entity)
            return "Successfully updated entity: $key | ${entity.name}"
        }
        return "No entity with this id: $key"
    }

    fun remove(key: Long): String {
        if (cache[key] != null) {
            cache.remove(key)
            return "Successfully removed entity: $key"
        }
        return "No entity with this id: $key"
    }

    @PreDestroy
    fun destroy() {
        cacheManager.stop()
    }
}

If i remove d1 values from Metadata annotation or write SimpleEntity and SimpleEntitySchema in Java, everything works fine, as it should.
