When running server classToLaunch cannot be null error occurs.

Caused since jboss 4.2 launch config's suddenly does not contain any launch info anymore:
Now:
<?xml version="1.0" encoding="UTF-8"?>
<launchConfiguration type="org.jboss.ide.eclipse.as.core.server.startupConfiguration">
<stringAttribute key="server-id" value="10_1_07_2_28_PM2"/>
</launchConfiguration>

Before:
<?xml version="1.0" encoding="UTF-8"?>
<launchConfiguration type="org.jboss.ide.eclipse.as.core.server.startupConfiguration">
<booleanAttribute key="jboss.defaults.been.set" value="true"/>
<listAttribute key="org.eclipse.jdt.launching.CLASSPATH">
<listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry externalArchive="/home/max/rhdevstudiob2/jboss-eap/jboss-as/bin/run.jar" path="3" type="2"/> "/>

<listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry externalArchive="/usr/java/jdk1.5.0_12/lib/tools.jar" path="3" type="2"/> "/>
</listAttribute>
<booleanAttribute key="org.eclipse.jdt.launching.DEFAULT_CLASSPATH" value="false"/>
<stringAttribute key="org.eclipse.jdt.launching.MAIN_TYPE" value="org.jboss.Main"/>
<stringAttribute key="org.eclipse.jdt.launching.PROGRAM_ARGUMENTS" value="--configuration=default"/>
<stringAttribute key="org.eclipse.jdt.launching.WORKING_DIRECTORY" value="/home/max/rhdevstudiob2/jboss-eap/jboss-as/bin"/>

</launchConfiguration>
