Has anyone seen an error like this when using the Deeplink module? If you are already logged in the link works as expected, but if you are not logged in it displays a blank page and generates this console error: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoaderJava5) previously initiated loading for a different type with name "javax/servlet/http/HttpServletRequest" Full stacktrace below: An unhandled error occurred in the MxRuntime. java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoaderJava5) previously initiated loading for a different type with name "javax/servlet/http/HttpServletRequest" at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.findClass(BundleWiringImpl.java:2279) at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1501) at org.apache.felix.framework.BundleWiringImpl.access$400(BundleWiringImpl.java:75) at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:1955) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at deeplink.actions.StartDeeplinkJava$DeepLinkHandler.serveLogin(StartDeeplinkJava.java:321) at deeplink.actions.StartDeeplinkJava$DeepLinkHandler.serveDeeplink(StartDeeplinkJava.java:181) at deeplink.actions.StartDeeplinkJava$DeepLinkHandler.processRequest(StartDeeplinkJava.java:152) at com.mendix.externalinterface.connector.MxRuntimeConnector$1.execute(MxRuntimeConnector.java:81) at com.mendix.externalinterface.connector.MxRuntimeConnector$1.execute(MxRuntimeConnector.java:78) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:37) at com.mendix.externalinterface.connector.MxRuntimeConnector.processRequest(MxRuntimeConnector.java:77) at com.mendix.core.impl.MxRuntimeImpl.processRequest(MxRuntimeImpl.java:786) at com.mendix.m2ee.appcontainer.server.handler.RuntimeHandler.handle(RuntimeHandler.java:45) at org.eclipse.jetty.server.handler.HandlerList.handle(HandlerList.java:52) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.Server.handle(Server.java:368) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:489) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:942) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:1004) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:640) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:235) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:82) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:628) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:52) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543) at java.lang.Thread.run(Thread.java:745) Has something changed in 5.15.1 to cause this error?

From your list of jars, I suspect servlet-api-3.0.jar and javax.servlet-3.0.0.jar are causing the issue and might conflict here . What is the reason for using these jars, are they related to a certain module?
The classloader is trying to load a servlet class, which has already been loaded and can't be accessed by the classloader.
Also, there are a couple of duplicate jars which potentially could cause conflicts. It is adviced to strip out the duplicates as much as possible.
E.g.
com.springsource.org.apache.commons.lang-2.5.0.jar
commons-lang-2.5.jar
commons-lang3-3.1.jar
com.google.guava-14.0.1.jar
guava-12.0.jar
slf4j-api-1.6.1.jar
slf4j-api-1.6.4.jar
