Grails starter configuration destroyed on Project Save

Hi,
since version 8, build #9013 (on Mac, if that makes a difference), my Grails starter config gets
mangled whenever the project is saved.
My original starter config is:

<configuration default="false" name="Pillarone development starter" type="Application" factoryName="Application" enabled="false" merge="false" sample_coverage="true" runner="emma">
      <option name="MAIN_CLASS_NAME" value="org.codehaus.groovy.grails.cli.support.GrailsStarter" />
      <option name="VM_PARAMETERS" value="-Xmx128m  -Dprogram.name=&quot;&quot; -Duser.language=&quot;de&quot; -Dgrails.home=&quot;../grails&quot; -Dbase.dir=&quot;.&quot; -Dgroovy.starter.conf=&quot;../grails/conf/groovy-starter.conf&quot; -Dtools.jar=&quot;../jre1.5.0_11/lib/tools.jar&quot;" />
      <option name="PROGRAM_PARAMETERS" value="--main org.codehaus.groovy.grails.cli.GrailsScriptRunner --conf &quot;../grails/conf/groovy-starter.conf&quot; --classpath &quot;.&quot; &quot;run-pillar-one&quot;" />

which works fine.
After a project save this becomes

<component name="ProjectRunConfigurationManager">
    <configuration default="false" name="Pillarone development starter" type="Application" factoryName="Application" enabled="false" merge="false" sample_coverage="true" runner="emma">
      <option name="MAIN_CLASS_NAME" value="org.codehaus.groovy.grails.cli.support.GrailsStarter" />
      <option name="VM_PARAMETERS" value="...jar&quot;" />
      <option name="PROGRAM_PARAMETERS" value=".&quot; &quot;run-pillar-one&quot;" />

which doesn't work at all.

ATM, I have a backup that I need copy over the original before every start of IntelliJ IDEA...

Any idea about the cause?

cheers
