Hi @pilgr

Thanks for the wonderful library, we are encountering a problem with the new android release.

When we try to read the database we get this error.

org.objenesis.instantiator.android.Android18Instantiator.findConstructorIdForJavaLangObjectConstructor (Android18Instantiator.java:72) org.objenesis.instantiator.android.Android18Instantiator.<init> (Android18Instantiator.java:39) org.objenesis.strategy.StdInstantiatorStrategy.newInstantiatorOf (StdInstantiatorStrategy.java:96) com.esotericsoftware.kryo.Kryo$DefaultInstantiatorStrategy.newInstantiatorOf (Kryo.java:1313) com.esotericsoftware.kryo.Kryo.newInstantiator (Kryo.java:1127) com.esotericsoftware.kryo.Kryo.newInstance (Kryo.java:1136) com.esotericsoftware.kryo.serializers.FieldSerializer.create (FieldSerializer.java:559) com.esotericsoftware.kryo.serializers.CompatibleFieldSerializer.read (CompatibleFieldSerializer.java:72) com.esotericsoftware.kryo.Kryo.readClassAndObject (Kryo.java:816) com.esotericsoftware.kryo.serializers.CollectionSerializer.read (CollectionSerializer.java:134) com.esotericsoftware.kryo.serializers.CollectionSerializer.read (CollectionSerializer.java:40) com.esotericsoftware.kryo.Kryo.readObject (Kryo.java:734) com.esotericsoftware.kryo.serializers.ObjectField.read (ObjectField.java:125) com.esotericsoftware.kryo.serializers.FieldSerializer.read (FieldSerializer.java:540) com.esotericsoftware.kryo.Kryo.readObject (Kryo.java:712) io.paperdb.DbStoragePlainFile.readTableFile (DbStoragePlainFile.java:248) io.paperdb.DbStoragePlainFile.readTableFile (DbStoragePlainFile.java:257) io.paperdb.DbStoragePlainFile.readTableFile (DbStoragePlainFile.java:235) io.paperdb.DbStoragePlainFile.select (DbStoragePlainFile.java:147) io.paperdb.Book.read (Book.java:67)

Have you got any idea on how can I fix it?

Which version of Paper do you use? How often it happens? Could you develop a unit test to reproduce the issue?
