- Subject: Proposed test on serialization back references
Hi,
for my first patch that I could commit myself, I prefer to ensure I'm
not doing something wrong and to begin with a trivial test (I got a more
interesting one with an actual classpath bug and the classpath fix that
I will add at the same time when I'll also get the write access on
classpath).
Thanks for the feedback.
2006-02-02 Olivier Jolly <olivier.jolly@pcedev.com>
* gnu/testlet/java/io/ObjectInputOutput/LoopSerializationTest.java:
New test on back references in serialization,
* gnu/testlet/java/io/ObjectInputOutput/SerializableLoopA.java: New
helper file,
* gnu/testlet/java/io/ObjectInputOutput/SerializableLoopB.java:
Likewise.
Regards,
Olivier
