> From the 3.6 thread RC2. We had issues in the release. Two tests failed. =
One of these tests happened on IBM JDK 8, and was related to time zones. Ga=
ry Gregory quickly pointed that the very latest IBM JDK 8 released did not =
had this issue.
> Indeed, I grabbed a JDK 8 from IBM and had this issue, and then after loo=
king for the latest version, I had only one test failing. This test in ques=
tion was ToStringBuilderTest#testReflectionHierarchyArrayList.
> Debugging the test in Eclipse, with the JDK pointing to IBM JDK 8 (and ta=
king care to not let the Eclipse maven integration change it), there is a p=
art of the code that receives an ArrayList object to create a String with r=
eflection.
> In Oracle JDK 7, the object contains the default 10 empty positions, and =
thus the generated String is.
> {noformat}
> java.util.ArrayList@761a4a3d[elementData=3D{<null>,<null>,<null>,<null>,<=
null>,<null>,<null>,<null>,<null>,<null>},size=3D0,modCount=3D0]
> {noformat}
> But with IBM JDK 8, the ArrayList is empty, nada, and then I get the foll=
owing in the Eclipse debugger.
> {noformat}
> java.util.ArrayList@761a4a3d[elementData=3D{},size=3D0,modCount=3D0]
> {noformat}
> The test is - as commented in LANG-727 - a bit flaky. However, the expect=
ed string assumes ArrayList will have an initial 10 null values. So the pul=
l request in this issue simply creates an ArrayList with 10 initial capacit=
y :-) a na=C3=AFve approach, but that I believe fixes this test.

ng with the following set-ups:
