http://issues.apache.org/bugzilla/show_bug.cgi?id=44103 Summary: Ant classloader return input stream of the resource, but disallows class loading and get URL Product: Ant Version: 1.7.0 Platform: Other OS/Version: Windows XP Status: NEW Severity: major Priority: P2 Component: Core AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Start ANT using org.apache.tools.ant.Main class, specify something in the ANT classloader. Try to get resource from your custom classpath as stream - it is ok. Try to get resource URL from your custom class path - it returns null. Try to load class from your custom class path - it fails. Severity is major because it breaks using XML (JAXP) in standard way through DocumentBuilderFactory in case of specifying xerces.jar in ANT classpath. Factory can find properties file, defined in xerces.jar, but fails to load implementation class from it. ANT start script: %JAVA_HOME%\bin\java.exe -Xmx650M -cp %GLOBAL_BUILD_DIR%\3rdparty\xerces\xercesImpl.jar org.apache.tools.ant.Main -listener org.apache.tools.ant.listener.Log4jListener ANT task <java classname="AntClassLoaderTest" failonerror="true" fork="false" /> AntClassLoaderTest code ClassLoader cl = AntClassLoaderTest.class.getClassLoader(); URL url = cl.getResource("org/apache/xerces/jaxp/DocumentBuilderFactoryImpl.class"); System.out.println("URL = " + url); InputStream in = cl.getResourceAsStream("org/apache/xerces/jaxp/DocumentBuilderFactoryImpl.class"); System.out.println("in = " + in); byte[] buf = new byte[16]; in.read(buf); boolean equals = Arrays.equals(buf, new byte[]{(byte) 0xCA, (byte) 0xFE, (byte) 0xBA, (byte) 0xBE, 0x00, 0x03, 0x00, 0x2D, 0x00, (byte) 0x8B, 0x0A, 0x00, 0x29, 0x00, 0x47, 0x09});
