[jira] [Created] (HTTPCORE-323) Uncaught
UnsupportedCharsetException in
org.apache.http.entity.ContentType.getOrDefault
Viktor created HTTPCORE-323:
-------------------------------
Summary: Uncaught UnsupportedCharsetException in org.apache.http.entity.ContentType.getOrDefault
Key: HTTPCORE-323
URL: https://issues.apache.org/jira/browse/HTTPCORE-323
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.2.2
Environment: Ubuntu Linux 12.10,
Sun Java 1.7.0
Linux kernel 3.5.0-19-generic i686
Reporter: Viktor
I have an wrong instance of HttpEntity, with illegal field "charset" (Content-Type: text/html; charset=cp-1251) in Content-Type header, and if ContentType.getOrDefault(entity) callied with that entity - method throwing an uncaught exception:
java.nio.charset.UnsupportedCharsetException: cp-1251
at java.nio.charset.Charset.forName(Charset.java:543)
at org.apache.http.entity.ContentType.create(ContentType.java:180)
at org.apache.http.entity.ContentType.create(ContentType.java:190)
at org.apache.http.entity.ContentType.get(ContentType.java:233)
at org.apache.http.entity.ContentType.getOrDefault(ContentType.java:249)
at org.apache.http.util.EntityUtils.toString(EntityUtils.java:212)
at org.apache.http.util.EntityUtils.toString(EntityUtils.java:264)
at com.rinamika.riwl.crawler.impl.LoaderImpl.processPage(LoaderImpl.java:131)
...
I suppose that it's not right behavior because method getOrDefault must be return a defaul value if something happend.
Sorry for my English.

[jira] [Commented] (HTTPCORE-323) Undocumented
UnsupportedCharsetException in
org.apache.http.entity.ContentType.getOrDefault
Posted by "Gary Gregory (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HTTPCORE-323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13504113#comment-13504113 ]
Gary Gregory commented on HTTPCORE-323:
---------------------------------------
Hello Viktor:
The Javadoc states:
/**
* Extracts <code>Content-Type</code> value from {@link HttpEntity} or returns default value
* if not explicitly specified.
*
* @param entity HTTP entity
* @return content type
* @throws ParseException if the given text does not represent a valid
* <code>Content-Type</code> value.
*/
So to me, the behavior you see is poorly documented:
* Extracts <code>Content-Type</code> value from {@link HttpEntity} or returns default value
* if not explicitly specified.
- You pass in a content type, so you 'specify' one which is why the default is not returned. That's part is fine.
* @throws ParseException if the given text does not represent a valid
* <code>Content-Type</code> value.
You pass in an invalid content type, but the method does not throw a ParseException.
BUT the throws declaration does specify UnsupportedCharsetException, it is not in the Javadoc though.
All of this tells me that we need better Javadocs.
See:
