Error while trying to deploy portlets

I'm trying to build last version of jetspeed-2 from source. But error occures on demo portlets deployment phase: "ERROR 23502: Column 'MAPPED_NAME' cannot accept a NULL value."

I'm following instructions on page: http://wiki.apache.org/portals/Jetspeed2/QuickstartForTheImpatient/BuildUsingMaven

So, my actions is:
1) I've installed JDK 1.5.0 to C:\Program Files\Java\jdk1.5.0_06

2) I've copied Maven 1.0.2 and Tomcat 5.5.17 to d:\java\bin

3) I've setted next variables:
JAVA_HOME=C:\Program Files\Java\jdk1.5.0_06;
JRE_HOME=C:\Program Files\Java\jdk1.5.0_06\jre;MAVEN_HOME=d:\java\bin\maven-1.0.2;
CATALINA_HOME=D:\java\bin\apache-tomcat-5.5.17

4) I've been downloading sources by "svn co
http://svn.apache.org/repos/asf/portals/jetspeed-2/trunk jetspeed-2" in folder d:\java\src

5) I've Modified my tomcat_users.xml, and now it contains:
<tomcat-users>
<role rolename="manager" />
<user name="tomcat" password="tomcat" roles="tomcat" />
<user name="role1" password="tomcat" roles="role1" />
<user name="both" password="tomcat" roles="tomcat,role1" />
<user username="j2deployer" password="j2deployer" roles="manager" />
</tomcat-users>

6) I've been downloading sources by "svn co
http://svn.apache.org/repos/asf/portals/jetspeed-2/trunk portals-jetspeed-2" in folder d:\java\src

7) I've modified file D:\java\src\portals-jetspeed-2\build.properties:
org.apache.jetspeed.server.home=D:/java/bin/apache-tomcat-5.5.17
org.apache.jetspeed.server.shared=D:/java/bin/apache-tomcat-5.5.17/shared/lib
org.apache.jetspeed.deploy.war.dir=D:/java/bin/apache-tomcat-5.5.17/webapps
org.apache.jetspeed.services.autodeployment.user=j2deployer
org.apache.jetspeed.services.autodeployment.password=j2deployer
org.apache.jetspeed.catalina.version.major=5.5
org.apache.jetspeed.project.home=D:/java/src/portals-jetspeed-2
org.apache.jetspeed.portal.home=D:/java/src/portals-jetspeed-2
maven.proxy.host=proxy.mycompany.net
maven.proxy.port=3128
jetspeed2.home=D:/java/src/portals-jetspeed-2

8) from folder d:\java\src\portals-jetspeed-2 i've runned commands
maven initMavenPlugin
maven allClean allBuild
maven j2:quickStart

9) %CATALINA_HOME%\bin\catalina run
I have an error on console:
