inconvertible types error when compiling binding-gdata-runtime
---------------------------------------------------------------
Key: TUSCANY-2544
URL: https://issues.apache.org/jira/browse/TUSCANY-2544
Project: Tuscany
Issue Type: Bug
Affects Versions: Java-SCA-Next
Environment: Win XP SP2 IBM JDK 1.5
Reporter: Simon Laws
Fix For: Java-SCA-Next
During clean compile of binding-gdata-runtime. I get.
C:\simon\tuscany\java-trunk\sca\modules\binding-gdata-runtime\src\test\java\org\
apache\tuscany\sca\binding\gdata\consumerprovider\CustomerClientImpl.java:[108,4
6] inconvertible types
found : com.google.gdata.data.BaseFeed<capture of ? extends com.google.gdata.d
ata.BaseFeed,capture of ? extends com.google.gdata.data.BaseEntry>
required: com.google.gdata.data.Feed
The line causing the problem is
Feed feed = (Feed) resourceCollection.getFeed();
There are many references on the net to these kinds of errors where generics
are cast up. Needs more investigation as to whether this is a compiler specific
funny.
Forcing the generics out of the picture using something like
Feed feed = (Feed)(Object) resourceCollection.getFeed();
Does work but is obviously not good.
