Subject [jira] [Updated] (CXF-7371) Error creating a webservice with lambdas in the implementing class
Date Sun, 30 Jul 2017 23:42:01 GMT

     [ https://issues.apache.org/jira/browse/CXF-7371?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Barnabas Bodnar updated CXF-7371:
---------------------------------
    Attachment: CXF-7371.zip

Sorry for the missing preconditions.
The problem occurs only with the simple frontend (demo-app attached), which attempts to determine
the names of the input-parameters extracting parameter-names from the debug-info of the service-class.
That is a self-made class-parser, obviously not supporting Java-8 bytecode.
