[rules-dev] LiteralRestriction NPE

Found a NullPointerException when using the verifier module. LiteralRestriction.setValue blows chunks, when the value is null. It sucks that Double.parseDouble doesn't behave the same as Integer.parseInt which handles nulls. java.lang.NullPointerException at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:991) at java.lang.Double.parseDouble(Double.java:510) at org.drools.verifier.components.LiteralRestriction.setValue(LiteralRestriction.java:128) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:688) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:123) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:572) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:562) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:119) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:482) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:183) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:529) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:113) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:482) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:410) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:111) at org.drools.verifier.PackageDescrFlattener.flatten(PackageDescrFlattener.java:389) at org.drools.verifier.PackageDescrFlattener.addPackageDescrToData(PackageDescrFlattener.java:96) at org.drools.verifier.Verifier.addPackageDescr(Verifier.java:32) at com.sungard.cmdb.generator.RuleGenerator.createValidationPackage(RuleGenerator.java:370) at com.sungard.cmdb.generator.RuleGenerator.generateCode(RuleGenerator.java:273) at com.sungard.cmdb.generator.JarBasedCodeGenerator.main(JarBasedCodeGenerator.java:156)
