Hi All,
        I'm getting some wierd exception while trying to insert a fact. I'm trying to compare a string field in a rule, like metricclass == "PROCESSOR"

java.lang.RuntimeException: Exception jitting: metricclass == "PROCESSOR"

Can someone tell me the possible causes. This happens with very few facts making it even more confusing. Thanks in advance
