Subject [jira] [Commented] (UIMA-4554) JCasGen generating rawType warnings for fsGenerator
Date Fri, 21 Aug 2015 20:46:46 GMT

    [ https://issues.apache.org/jira/browse/UIMA-4554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14707432#comment-14707432
] 

Richard Eckart de Castilho commented on UIMA-4554:
--------------------------------------------------

I have had a look at the patch and I think it looks pretty good in general. 

I am unsure about one change:

{noformat}
<% if ("Annotation".equals(jg.getJavaName(td.getSupertypeName()))) {%>
  @SuppressWarnings({ "rawtypes", "unchecked" })
<% } else {%>
  @SuppressWarnings("rawtypes")
<% } %>
{noformat}

This looks like potential trouble for two reasons:

* if checks the short class name without the package name. Maybe a check like {{<% if (td.getName().equals("uima.cas.Annotation"))
{ %>}} would be more adequate?
* it checks the the immediate supertype - what about types that have 1+ intermediate supertypes
until "Annotation" is reached

Anyway, wouldn't it be possible to use the correct parametrization instead of using @SuppressWarnings("rawtypes")?

Another comment would be that the patch actually seems to address multiple unrelated problems:

# the "FSGenerator is a raw type. References to generic type FSGenerator<T> should be
parameterized AAA_Type.java" warnings 
# the warnings about the unnecessary @SuppressWarnings("rawtypes")
# the problem that the jet-expander module doesn't work on Linux/OS X

Normally, I would suggest to have separate issues for these and separate patches - but a at
least the first two were discussed in this issue and the last one is easy to separate out
when we apply the patch.

> JCasGen generate references to FsGenerator which was changed in 2.8.0 to have generic
type information.  So the resulting generated code causes warnings about raw types being used.
 Workaround - add a @SuppressWarnings("rawtypes"), but a better thing would be to add the
proper generic arguments.
