DefaultExecutorService: No possibility to set ClassLoader used for cloning Callables ------------------------------------------------------------------------------------ Key: ISPN-2841 URL: https://issues.jboss.org/browse/ISPN-2841 Project: Infinispan Issue Type: Enhancement Components: Clustered Executor Affects Versions: 5.2.1.Final Reporter: Carsten Lohmann Assignee: Galder Zamarreño When using the DistributedExecutorService we noticed that the ContextClassLoader of the current thread is used for cloning the Callable. But this ClassLoader wasn't able to find the Callable class in our case, so we got this exception: {noformat} org.infinispan.CacheException: java.lang.ClassNotFoundException: [...]Callable at org.infinispan.util.Util.cloneWithMarshaller(Util.java:259) at org.infinispan.distexec.DefaultExecutorService.clone(DefaultExecutorService.java:555) at org.infinispan.distexec.DefaultExecutorService.submitEverywhere(DefaultExecutorService.java:510) at org.infinispan.distexec.DefaultExecutorService.submitEverywhere(DefaultExecutorService.java:497) [...] Caused by: java.lang.ClassNotFoundException: [...]Callable at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.jboss.marshalling.AbstractClassResolver.loadClass(AbstractClassResolver.java:135) at org.jboss.marshalling.AbstractClassResolver.resolveClass(AbstractClassResolver.java:116) at org.jboss.marshalling.river.RiverUnmarshaller.doReadClassDescriptor(RiverUnmarshaller.java:893) at org.jboss.marshalling.river.RiverUnmarshaller.doReadNewObject(RiverUnmarshaller.java:1205) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:272) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:209) at org.jboss.marshalling.AbstractObjectInput.readObject(AbstractObjectInput.java:37) at org.infinispan.marshall.jboss.AbstractJBossMarshaller.objectFromObjectStream(AbstractJBossMarshaller.java:163) at org.infinispan.marshall.VersionAwareMarshaller.objectFromByteBuffer(VersionAwareMarshaller.java:116) at org.infinispan.marshall.AbstractMarshaller.objectFromByteBuffer(AbstractMarshaller.java:106) at org.infinispan.marshall.AbstractDelegatingMarshaller.objectFromByteBuffer(AbstractDelegatingMarshaller.java:99) at org.infinispan.util.Util.cloneWithMarshaller(Util.java:254) {noformat} So there should be a possibility to explicitly set the ClassLoader that the ExecutorService will use for cloning the Callable. Maybe by using the ClassLoader set via AdvancedCache.with(ClassLoader) on the AdvancedCache given to the ExecutorService.
