Hi, Just fyi, when you're re-using BpelCompiler20 instance, expression languages (at least xpath 2.0) don't get listed to OProcess#expressionLanguages--except for the first compilation. This results to null return values from ExpressionLanguageRuntimeRegistry#findRuntime(..) and thus npes (with the rest of the compilations, that is.) Just my two cents.. :)
