[rules-users] Disabling strict mode in 5.4

How do you disable strict mode in 5.4? We are using the code below and getting strict mode exceptions. It worked in prior versions. Do you have to use the new APIs to disable strict mode? PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration(); MVELDialectConfiguration mvelConf = (MVELDialectConfiguration) pkgBuilderCfg.getDialectConfiguration( "mvel" ); mvelConf.setStrict(false); mvelConf.setLangLevel(5); PackageBuilder builder = new PackageBuilder(pkgBuilderCfg); builder.addPackageFromDrl(new StringReader(drlString)); An example exception: 1. 19:17:51,137|ERROR|drools.DroolsMgr|DroolsMgr.java|159|deployRulesFromMo delForScope|org.apache.camel.spring.Main.main()|smf-rcp-SNAPSHOT|Failed to deploy rules from model 2. com.recondotech.hre.rules.management.HRERulesManagmentException: org.drools.rule.InvalidRulePackage: Unable to Analyse Expression $existingValue.toLowerCase(): 3.
