This reproducer fails on my machine with a StackOveflowException when serializing ( not de-serializing ). It fails with: Exception in thread "main" java.lang.StackOverflowError at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1142) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1577) at java.base/java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1534) at java.base/java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1443) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1186) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1577) at java.base/java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1534) at java.base/java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1443) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1186) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1577) at java.base/java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1534) at java.base/java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1443) at java.base/java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1186) at java.base/java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1577) ... The same is true if Link is a normal class ( not a record class ). Records and normal classes share the same code path in OOS when serializing. -Chris.
