Doing a smoke test for the release of 4.4.3.AM2 when I saw this error:
!ENTRY org.eclipse.mylyn.tasks.core 4 0 2017-02-01 16:23:23.127 !MESSAGE Unexpected error while loading repository template extensions !SUBENTRY 1 org.eclipse.mylyn.tasks.core 4 0 2017-02-01 16:23:23.127 !MESSAGE Could not load repository template extension contributed by 'org.jboss.tools.common.mylyn' with connectorKind 'jira'
I saw this in the log after performing the following:
0. Downloaded Neon.2 (I happened to choose the C/C++ distribution)
1. Install Abridged category from http://download.jboss.org/jbosstools/neon/development/updates/
2. Open Central Software/Updates tab, enable Early Access select and install everything
