While parsing arguments for a DAX job, pegasus does not parse -Dpropertyname=value option correctly.
Since 3.0 users can addition to specifying pegasus properties, can specify profiles as properties for example -Ddagman.datafind.maxjobs

<dax id="ID000026" file="inspiral_hipe_bnsloginj_cat3_veto.BNSLOGINJ_CAT_3_VETO.dax">
<argument>-Dpegasus.dir.storage=bnsloginj -Ddagman.datafind.maxjobs=10 -Ddagman.sire.maxjobs=20 -Ddagman.coire.maxjobs=20 -Ddagman.thinca.maxjobs=20 -Ddagman.trigbank.maxjobs=20 --dir bnsloginj --nocleanup --cluster horizontal -vvvvvv --force</argument>
</dax>

When pegasus plans this DAX job the dagman properties disappear from the pre script invocation
