Drools 3.1.M1 Rules build results in java.lang.UnsupportedOperationException

Initial issue description sent in following email test:
yep - looks like a bug to me on a quick look - do you want to attach a simple test to a JIRA?

Getting exception below building rules that build in 3.0.4.
Looking at FunctionBuilder we have at line 106. The code in red looks suspicious? Seems it should be mapping "mapping" against the name.
But that is not what is the cause of the exception apparently put is not supported?
String name = pkg.getName() + "." + ucFirst( functionDescr.getName() );
LineMappings mapping = new LineMappings( name );
mapping.setStartLine( functionDescr.getLine() );
mapping.setOffset( functionDescr.getOffset() );
lineMappings.put( name, lineMappings );

A second problem is the cause of the UnsupportedOperationException turns out to be our use of the PackageBuilder in 3.0.4 that is no longer supported by 3.1.M1. We are using the merge rules constructor when we create a rule package from scratch as follows:
this.droolsPackage = new org.drools.rule.Package(packageName);
PackageBuilderConfiguration config = new PackageBuilderConfiguration();
config.setJavaLanguageLevel("1.5");
this.packageBuilder = new PackageBuilder(droolsPackage, config);
This used to work before but in version 3.1.M1 in PackageBuilder the Map lineMappings is only initialized with a HashMap when the newPackage() method is invoked and not when the mergePackage() method is invoked. The assumption is the lineMappings has been initialized when mergePackage() has been invoked.
Changing to properly use from scratch and merge constructors

but if I remove some rules everything works fine.
