Sergey Beryozkin commented on CXF-3719: --------------------------------------- thanks for the above analysis, for the moment, please configure JSONProvider explicitly and use ignoreNamespaces property. I'll work on this issue asap > NullPointerException When using TransformOutInterceptor > ------------------------------------------------------- > > Key: CXF-3719 > URL: https://issues.apache.org/jira/browse/CXF-3719 > Project: CXF > Issue Type: Bug > Components: JAX-RS > Affects Versions: 2.4.1 > Environment: Linux 2.6.29, java 1.6.0_16 > Reporter: Christopher Marshall > > I have attempted to remove the namespace prefixes outbound JSON messages by > using the TransformOutInterceptor. At line 87 it explicitly does > message.removeContent(OutputStream.class); > and this eventually causes a NullPointerException in the constructor of > java.io.Writer. The MessageImpl class has an array called defaultContents > that would have otherwise had an entry containing > HTTPConduit$WrappedOutputStream that would have been passed through multiple > layer to the constructor of java.io.writer. -- This message is automatically generated by JIRA.
