JDK version and platform:java version "1.6.0_29" Java(TM) SE Runtime Environment (build 1.6.0_29-b11) Oracle JRockit(R) (build R28.2.0-79-146777-1.6.0_29-20111005-1808-windows-ia32, compiled mode)
Description
If a complex object uses another object that extends HashMap<String, String> during the serialization a new field is inserted in the xml when running on Weblogic/JRockit what makes it impossible to deserialze it on another JVM/Application server.
typeSettingsProperties is an instance of UnicodeProperties which extends HashMap<String, String>
On Tomcat with other JVM it seems to be OK.
Here is an example snippet:
<__typeSettingsProperties serialization="custom"> <unserializable-parents/> <map> <default> <cache__bitmask>-1</cache__bitmask> <!-- This line cause trouble --> <loadFactor>0.75</loadFactor> <threshold>12</threshold> </default> <int>16</int> <int>2</int> <string>layout-template-id</string> <string>2_columns_ii</string> <string>column-1</string> <string>56_INSTANCE_e5cZUX98hCmA</string> </map> <com.liferay.portal.kernel.util.UnicodeProperties> <default> <__length>66</__length> <__safe>true</__safe> </default> </com.liferay.portal.kernel.util.UnicodeProperties> </__typeSettingsProperties>
If an XML is exported from Weblogic and tried to import into the same webapplication running on Tomcat this StackTrace is shown:

Vilmos Hi Jörg,
I decompiled the HashMap implementation of JRockit and Oracle/Sun JVM, and it is an exact difference between them, that the JRockit version has a
private int cache_bitmask;
field. So the problem originates from the JAVA implementation in JRockit not form our code.
This seems to be a compatibility issue with JRockit R28.
Could you verify it whether it can be patched or not?

Sorry, this statement does not make any sense to me. The solution is still the same. Register an own converter for UnicodeProperties.

This is normal. XStream uses specialized converters for known types only, all other ones are handled by the reflection-based converters which will reflect any implementation specific detail in the XML structure. This includes differences between different JDK versions or JDKs from different vendors.
If you want to prevent this behavior for UnicodeProperties, you will have to register your own converter that can handle this type. You may simply derive from the MapConverter.
