Subject [jira] Created: (MYFACES-1498) Myfaces core not 1.4 compatible
Date Mon, 20 Nov 2006 20:40:03 GMT
Myfaces core not 1.4 compatible
-------------------------------

                 Key: MYFACES-1498
                 URL: http://issues.apache.org/jira/browse/MYFACES-1498
             Project: MyFaces Core
          Issue Type: Bug
          Components: General
    Affects Versions: 1.1.3
         Environment: IBM Java 1.4.2
            Reporter: Janne Kario
            Priority: Minor


I stubled upon this NoSuchMethodError and did a google search and found out that other people
on myfaces-user have had this problem too.

As described in http://thicksliced.blogspot.com/2006/04/compiling-for-older-jvms.html the
problem is StringBuffer.insert call in _SelectItemsIterator.java:228

My guess is that myfaces-core-1.1.3 release was compiled with 1.5.0 compiler using source="1.4"
and target="1.4" switches. Can someone confirm this?
Apparently this alone is not enough to guarantee complete 1.4 compatibility.

I will recompile 1.1.4 myself with 1.4 compiler to confirm this.

There is also a workaround that can be applied in the source level. Cast the second argument
of the insert call to Object. insert(2, (Object)strBuf)
