After installing jslint4java and trying to validate a large project, Eclipse crashed and wouldn't restart, giving the error:
Job found still running after platform shutdown. Jobs should be canceled by the plugin that scheduled them during shutdown
Starting Eclipse with
eclipse -clean
did not solve the problem so you will need to remove the file [WORKSPACE]/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
rm /home/chris/workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
