    If you run some tasks from com.atlassian.sal.api.scheduling.PluginScheduler them will be runned with WebappClassloader. If your plugin job try to check merge vetos for other pull request via com.atlassian.stash.scm.pull.MergeRequestCheckService in this job thread, then all MergeChecks will executed not in http-threads-xxx, bu in other threads. And then, if you try to serialize ListHashMultimap in some of this MergeChecks (other plugins), you may get strange exception: {code} 2014-02-10 01:46:42,645 WARN [scheduler_Worker-5] java.lang.ClassNotFoundException: com.acme.stash.plugin.other.content.SomeKeyInSetMultimap at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702) ~[catalina.jar:7.0.47] at java.lang.Class.forName0(Native Method) ~[na:1.6.0_45] at java.lang.Class.forName(Class.java:249) ~[na:1.6.0_45] at java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:602) ~[na:1.6.0_45] at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1589) ~[na:1.6.0_45] at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1494) ~[na:1.6.0_45] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1748) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1327) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:349) ~[na:1.6.0_45] at com.google.common.collect.Serialization.populateMultimap(Serialization.java:184) ~[guava-10.0.1.jar:na] at com.google.common.collect.LinkedHashMultimap.readObject(LinkedHashMultimap.java:383) ~[guava-10.0.1.jar:na] at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:969) ~[na:1.6.0_45] at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1871) ~[na:1.6.0_45] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1775) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1327) ~[na:1.6.0_45] at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1969) ~[na:1.6.0_45] at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1893) ~[na:1.6.0_45] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1775) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1327) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:349) ~[na:1.6.0_45] at java.util.HashSet.readObject(HashSet.java:291) ~[na:1.6.0_45] at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:969) ~[na:1.6.0_45] at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1871) ~[na:1.6.0_45] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1775) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1327) ~[na:1.6.0_45] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:349) ~[na:1.6.0_45] ...

I think, that PluginScheduler load tasks in not valid ClassLoader.
