The problem is that IBM 1.4.1 bundles xerces.jar, which masks the xerces that is shipped with Eclipse. In IBM's xerces, the method DOMBuilder.setFeature() that we depend on for parsing manifest files is not found and hence the exception. Until this defect is resolved, I advise you to use Sun's 1.4.x *** This bug has been marked as a duplicate of 39187 ***
