Looks like the logic in UdfManager.getFunctionLibrary() needs some tweaking because the first time it's called, changed == FALSE

public synchronized FunctionLibrary getFunctionLibrary() {
//System.out.println("UdfManger.getFunctionLibrary()");
if( !changed )

{ return this.cachedFunctionLibrary; }

change to:

public synchronized FunctionLibrary getFunctionLibrary() {
//System.out.println("UdfManger.getFunctionLibrary()");
if( !changed && this.cachedFunctionLibrary != null ) { return this.cachedFunctionLibrary; }
