[castor-user] java.lang.StackOverflowError when unmarshalling document with > 2 nested elements

Mon, 11 Oct 2004 06:10:02 -0700 

Hi,

Unmarshalling the following xml document causes a java.lang.StackOverflowError. The document has 3 nested Node elements. If I remove the 3rd nested element the document is marshalled correctly. I am not using a mappings file.

<?xml version="1.0" encoding="UTF-8"?>
<MgmtTree>
<VerDTD>ver 2.0</VerDTD>
<Man>-- Nokia --</Man>
<Mod>String</Mod>
<Node>
<NodeName>SyncML</NodeName>
<Path>./</Path> <DFProperties>
<AccessType>
<Get/>
</AccessType>
<DefaultValue>String</DefaultValue>
<Description>String</Description>
<DFFormat>
<b64/>
</DFFormat>
<Occurrence>
<One/>
</Occurrence>
<Scope>
<Permanent/>
</Scope>
<DFTitle>SyncML object</DFTitle>
<DFType>
<MIME>basic</MIME>
</DFType>
</DFProperties>
<Node>
<NodeName>DMAcc</NodeName> <Path>/syncml</Path>
<DFProperties>
<DFTitle>A collection of all SyncML DM accounts</DFTitle>
<AccessType><Add/></AccessType>
<DefaultValue>hello</DefaultValue>
<Description>description</Description>
<DFFormat><b64/></DFFormat>
<DFType><DDFName>myddfname</DDFName></DFType>
</DFProperties>
<Value>my nested value</Value> <Node>
<NodeName>DMAcc</NodeName> <Path>/syncml</Path>
<DFProperties>
<DFTitle>A collection of all SyncML DM accounts</DFTitle>
<AccessType><Add/></AccessType>
<DefaultValue>hello</DefaultValue>
<Description>description</Description>
<DFFormat><b64/></DFFormat>
<DFType><DDFName>myddfname</DDFName></DFType>
</DFProperties>
<Value>my nested value</Value> </Node>
</Node>
</Node>
</MgmtTree>

The xml shema for this document is attached.

Any help in this matter would be much appreciated.
