Why does createOrUpdatePath API fail with incompatible data type errors ?

Issue

• createOrUpdatePath API fails with "java.lang.Integer incompatible with java.lang.Boolean "
• catalina.out errors :

Caused by:
java.lang.ClassCastException: java.lang.Integer incompatible with java.lang.Boolean
        at com.redhat.rhn.frontend.xmlrpc.configchannel.XmlRpcConfigChannelHelper.createOrUpdatePath(XmlRpcConfigChannelHelper.java:134)
        at com.redhat.rhn.frontend.xmlrpc.system.config.ServerConfigHandler.createOrUpdatePath(ServerConfigHandler.java:196)
        ... 41 more

The API is :

my %path_info;
$path_info{'contents'} = encode_base64(`cat $local_file`);
$path_info{'contents_enc64'} = 1;
$path_info{'owner'} = $client->string('root');
$path_info{'group'} = $client->string('root');
$path_info{'permissions'} = $client->string('644');
$path_info{'macro-start-delimiter'} = '';
$path_info{'macro-end-delimiter'} = '';
# 'system_u:object_r:etc_t:s0'
$path_info{'selinux_ctx'} = $selinux_ctx;
$path_info{'revision'} = '';

• createOrUpdatePath API fails with error "java.lang.Integer incompatible with java.lang.String"

  The API is :

fileStruct = {"contents" : fileInfo[0]["contents"], "owner" : fileInfo[0]["owner"], "group" : fileInfo[0]["owner"], "permissions" : fileInfo[0]["permissions"], "revision" : fileInfo[0]["revision"]}           

client.configchannel.createOrUpdatePath(key, channel, path[0], 0, fileStruct)
