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; } -- This message is automatically generated by JIRA.
