    In preparation for an upgrade to our primary Nexus (back at version 1.8.0.1), I've copied the working dir and run up a fresh nexus download against it (2.6.4-02). It seems to start up OK, but then when hitting localhost:8087/nexus (I changed the port in nexus.properties), all I get is a directory listing (below) and /nexus/index.html returns a 404 {noformat}Directory: /nexus/ LICENSE.html 11946 bytes Oct 11, 2013 6:13:45 AM WEB-INF/ 512 bytes Oct 22, 2013 5:50:02 PM favicon.ico 1150 bytes Oct 11, 2013 4:38:14 AM favicon.png 1160 bytes Oct 11, 2013 4:38:14 AM images/ 512 bytes Oct 22, 2013 5:50:02 PM robots.txt 86 bytes Oct 11, 2013 4:38:14 AM {noformat} I do get a couple of exceptions in the wrapper.log, which up till now I've assumed are harmless and a result of the data upgrade. {code}jvm 1 | 2013-10-23 11:20:53 INFO [jetty-main-thread-1] org.sonatype.scheduling.DefaultTaskConfigManager - Loading task - Rebuild Maven Metadata Files jvm 1 | 2013-10-23 11:20:53 INFO [jetty-main-thread-1] org.sonatype.scheduling.DefaultTaskConfigManager - Loading task - Optimize Public Repository jvm 1 | 2013-10-23 11:20:53 WARN [jetty-main-thread-1] org.sonatype.scheduling.DefaultTaskConfigManager - Unable to initialize task Optimize Public Repository, couldn't load service class 13 jvm 1 | java.lang.IllegalArgumentException: Could not create task of typeOptimizeIndexTask jvm 1 | at org.sonatype.scheduling.DefaultTaskConfigManager.createTaskInstance(DefaultTaskConfigManager.java:269) [nexus-core-2.6.4-02.jar:2.6.4-02]{code} {code}jvm 1 | 2013-10-23 11:20:53 INFO [jetty-main-thread-1] org.sonatype.scheduling.DefaultTaskConfigManager - Loading task - Publish Indexes jvm 1 | 2013-10-23 11:20:53 WARN [jetty-main-thread-1] org.sonatype.scheduling.DefaultTaskConfigManager - Unable to initialize task Publish Indexes, couldn't load service class 3 jvm 1 | java.lang.IllegalArgumentException: Could not create task of typePublishIndexesTask {code} {code}jvm 1 | 2013-10-23 11:21:01 INFO [LegacyAttributesUpgrader] <unknown-user> org.sonatype.nexus.proxy.maven.maven2.M2Repository - Rebuilding item attributes in repository "Maven Central" [id=central] from path="/" jvm 1 | Exception in thread "LegacyAttributesUpgrader" java.lang.InstantiationError: java.util.Map$Entry jvm 1 | at sun.reflect.GeneratedSerializationConstructorAccessor101.newInstance(Unknown Source) jvm 1 | at java.lang.reflect.Constructor.newInstance(Constructor.java:526) jvm 1 | at com.thoughtworks.xstream.converters.reflection.Sun14ReflectionProvider.newInstance(Sun14ReflectionProvider.java:75) ... jvm 1 | at com.thoughtworks.xstream.XStream.fromXML(XStream.java:922) jvm 1 | at org.sonatype.nexus.proxy.attributes.LegacyFSAttributeStorage.doGetAttributes(LegacyFSAttributeStorage.java:276) ... jvm 1 | at org.sonatype.nexus.proxy.repository.AbstractRepository.recreateAttributes(AbstractRepository.java:599) jvm 1 | at org.sonatype.nexus.proxy.attributes.upgrade.AttributeUpgraderThread.run(AttributeUpgraderThread.java:162){code}
