Fisheye/Crucible is targeting JDK 1.7 compatibility for our next release. The ActiveObjects plugin is throwing errors on startup:
Detected an error (BundleException) enabling the plugin 'com.atlassian.activeobjects.activeobjects-plugin' : Unresolved constraint in bundle com.atlassian.activeobjects.activeobjects-plugin : Unable to resolve 14.0: missing requirement [14.0] package; (&(package=javax.xml.namespace)(version>=0.0.0.1_006_JavaSE)). This error usually occurs when your plugin imports a package from another bundle with a specific version constraint and either the bundle providing that package doesn't meet those version constraints, or there is no bundle available that provides the specified package. For more details on how to fix this, see http://confluence.atlassian.com/x/1xy6D
Hacking activeobjects-plugin-0.15.jar/META-INF/maven/com.atlassian.activeobjects/activeobjects-plugin/pom.xml to remove version>=0.0.0.1_006_JavaSE from javax.xml.namespace* and javax.xml.stream* seems to fix the problem, but we need to get it fixed properly.
