Description James Blackburn CLA 2011-01-13 11:28:17 EST 
Eclipse 3.7M4  (Eclipse SDK	3.7.0.I20101208-1300)

The line of code looks like:

SAXTransformerFactory factory = (SAXTransformerFactory) SAXTransformerFactory.newInstance();

I'm seeing the following API error:

Description	Resource	Path	Location	Type
The method SAXTransformerFactory.newInstance() referenced in org.eclipse.cdt.internal.ui.wizards.settingswizards.ProjectSettingsExportStrategy.finish(IProjectSettingsWizardPage) is not defined in the bundle's required execution environment: J2SE-1.5 	ProjectSettingsExportStrategy.java	/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/ui/wizards/settingswizards	line 95	API Usage Problem

According to:
http://download.oracle.com/javase/1.5.0/docs/api/javax/xml/transform/sax/SAXTransformerFactory.html
this method is defined as TransformerFactory.newInstance() which is extended by SAXTransformerFactory.


If I change this to:
TransformerFactory.newInstance();

The error goes away.

I have a Java 4, Java 5, and Java 6 execution environment installed. 

However I think this may be related to the PDE/API tools I've recently installed: 
    PDE/API Tools Environment Descriptions	1.0.100.v20101028-7C-7BF9JgLWLMBMMAMsLL

Could you please give me the exact bundle ids from the installation page ?

What version of CDT should I install to reproduce ?

configuration

attached is my current eclipse configuration.

I'm using Eclipse Classic 3.7M4 with PDE API Tools installed from here:
http://download.eclipse.org/releases/indigo

To see the CDT plugins where this occurs, checkout from:
dev.eclipse.org/cvsroot/tools
Two plugins (should be sufficient):
org.eclipse.cdt/all/org.eclipse.cdt.core
org.eclipse.cdt/all/org.eclipse.cdt.ui

The error occurs in cdt ui:
src/org/eclipse/cdt/internal/ui/wizards/settingswizards/ProjectSettingsExportStrategy.java
Comment 3 Olivier Thomann CLA 2011-01-13 12:54:19 EST 
Reproduced with a simple test case.
The problem comes from the fact that I don't do any lookup for static methods while checking the EEs defined for the project.
Working on it.
Comment 4 Olivier Thomann CLA 2011-01-13 13:11:14 EST 
In fact the compiler generates the actual receiver type even if the method is static and it is defined in a super class.
So we actually need a method lookup when resolving the static method for checking the EEs defined for the bundle.
