----------------------------------------

             Summary: Parsing persistence.xml throws premature end of file error
                 Key: OPENJPA-2791
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2791
             Project: OpenJPA
          Issue Type: Bug
          Components: build / infrastructure, jpa
    Affects Versions: 2.4.3
         Environment: Linux Ubuntu 18.04
            Reporter: Robert F. Peake


XMLMetaDataParser in org.apache.openjpa.lib.meta uses the SaxParser to read persistence.xml. Just within the last few days, it has begun to throw this error:
{quote}org.xml.sax.SAXException: [file:/home/robert/git/sccdata/target/classes/META-INF/persistence.xml|file:///home/robert/git/sccdata/target/classes/META-INF/persistence.xml] [Location: Line: 5, C: 64]: org.xml.sax.SAXParseException; systemId: [http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd]; lineNumber: 1; columnNumber: 1; Premature end of file.
{quote}
Resorting to XML Copy Editor to validate the schema shows the error actually involved: Fatal Error at line 0, column 0: unsupported protocol in URL. It seems that Oracle's web site has switched from HTTP to HTTPS, which is a protocol that parser cannot handle, as explained in this post:
