[xstream-user] Problem with AIX 7.1 (On XStream 1.4.4)

[Uri Shtand]

Hi.
Xstream 1.4.4 doesn't work correctly on AIX 7.1
I get the following exception

java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -1
                at
com.thoughtworks.xstream.core.util.OrderRetainingMap.entrySet(OrderRetainingMap.java:77)
                at java.util.HashMap.putAllImpl(HashMap.java:678)
                at java.util.HashMap.putAll(HashMap.java:669)
                at
com.thoughtworks.xstream.core.util.OrderRetainingMap.<init>(OrderRetainingMap.java:36)
                at
com.thoughtworks.xstream.converters.reflection.FieldDictionary.buildMap(FieldDictionary.java:135)

The problem doesn't happen on older versions of XStream, and doesn't happen
on AIX 5.3 or 6.1

Doing some analysis, It looks like the OrderRetainingMap is assuming things
about the implementation of Hashmap (which it extends) that are not true in
the AIX JRE that we're using (IBM Java 6 for AIX 7.1)
More specifically, it uses super.putAll and assumes that super.put is
called as a consequence (which usually happens, but not in AIX 7.1).

I've tried to open a bug, but couldn't figure out how to register to the
jira bug tracker (trying to log-in shows the wonderful message: Not a

Thanks in advance,
