VerifyError on Datastore Protobuf

[masoudsc]

My code is simply reading from one entity in Datastore. It works fine in V2.8 but I get this error when in 2.11

Exception in thread "main" java.lang.VerifyError: Bad type on operand stack

Can't reproduce with this snippet:

import com.google.common.collect.ImmutableMap
import com.google.datastore.v1.Entity
import com.google.datastore.v1.client.DatastoreHelper.{makeKey, makeValue}
import org.scalatest._

class DatastoreTest extends FlatSpec with Matchers {

  "Datastore" should "work" in {
    noException should be thrownBy {
      Entity.newBuilder()
        .setKey(makeKey("key"))
        .putAllProperties(ImmutableMap.of(
          "content", makeValue("value").build(),
          "int", makeValue(10).build()
        ))
        .build()
    }
  }

}

Can you provide one that causes the problem? Do you have a protobuf dependency conflict in your project?

Gonna close this for now. Feel free to re-open if you can provide a reproducible snippet.
