Patrick Dunne commented on THRIFT-2988: --------------------------------------- These are the same issue > Class Cast Exception in Generated Java AsyncProcessor > ----------------------------------------------------- > > Key: THRIFT-2988 > URL: https://issues.apache.org/jira/browse/THRIFT-2988 > Project: Thrift > Issue Type: Bug > Components: Java - Compiler, Java - Library > Reporter: deepankar > Priority: Critical > > When using a generated Async Processor for any service, there is a class cast > exception that can happen when you call the onError function on a returned > AsyncMethodCallback (returned from any class that extends > {{AsyncProcessFunction}}) with an exception other than the expected exception > for that method > This occurs because the org.apache.thrift.TApplicationException being cast as > (org.apache.thrift.TBase) in the generated code for a service > {code:title=Bar.java|borderStyle=solid} > indent(f_service_) << "{" << endl; > indent_up(); > indent(f_service_) << "msgType = > org.apache.thrift.protocol.TMessageType.EXCEPTION;" << endl; > indent(f_service_) << "msg = (org.apache.thrift.TBase)new " > > "org.apache.thrift.TApplicationException(org.apache.thrift." > "TApplicationException.INTERNAL_ERROR, > e.getMessage());" << endl; > indent_down(); > indent(f_service_) << "}" << endl; > {code} > link : [code-in-github-trunk > |https://github.com/apache/thrift/blob/master/compiler/cpp/src/generate/t_java_generator.cc#L3209-L3221] > There are two ways to solve this : > * one is make TApplicationException to extend TBase > * another is to change the code generation logic here > I can put up a patch based on what approach is advised ? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
