Steve Hodecker created CXF-4618:
-----------------------------------

             Summary: DataSourceProvider is not closing inputstream acquired 
from DataSource
                 Key: CXF-4618
                 URL: https://issues.apache.org/jira/browse/CXF-4618
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.7.0
         Environment: Windows
            Reporter: Steve Hodecker
         Attachments: DataSourceProvider.java.patch

When a REST method returns a DataSource, e.g.:

@GET
public DataSource getFile() { ...

...the CXF JAX-RS framework obtains an inputstream from the datasource but does 
 close the stream after use.  This is noticeable on windows environments for 
the case of a provided FileDataSource, since the underlying file cannot be 
deleted while this file handle remains open.

I've tracked down the problem to the writeTo() method of 
org.apache.cxf.jaxrs.provider.DataSourceProvider and will attach a proposed 
patch.
