testSerialize fails when running "ant test"

[Juul]

The offending line is:

assertEquals(annotation1.getStrand(), annotation2.getStrand());

In the method:

public void assertEqual(SequenceAnnotationImpl annotation1, SequenceAnnotationImpl annotation2)

The relevant output:

[junit] Testcase: testSerialize took 0.246 sec

Just a note about Java version:

java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.2) (6b22-1.10.2-0ubuntu1~11.04.1)
OpenJDK Server VM (build 20.0-b11, mixed mode)

This is my version (which does not fail):
Java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)

So, it's either Ubuntu or Oracle Java which makes the difference. Do you have an Ubuntu installation with Oracle's Java which you could try, just to see if that's the issue?
