             Summary: Fix {@literal @} that shows up in Javadoc code examples
                 Key: BEAM-6680
                 URL: https://issues.apache.org/jira/browse/BEAM-6680
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Jeff Klukas
            Assignee: Jeff Klukas


Many Beam classes include multi-line code examples. When annotations need to 
mark classes or methods in those examples, it looks like we have generally have 
tried to escape the `@` with a "@literal" tag, but those tags aren't working as 
expected and end up appearing in the rendered documentation. See 
[ParDo|https://beam.apache.org/releases/javadoc/2.10.0/org/apache/beam/sdk/transforms/ParDo.html]
 for several examples.

Where `@` appears within a line, no escaping appears to be necessary. It gets a 
bit complicated when `@` appears as the first non-whitespace character in a 
line, as is usually the case for annotations on classes or methods. I've 
proposed a style for handling that case in 
https://github.com/apache/beam/pull/7852
