I have been using Eclipse for many years (usually Jboss Developer Studio) and have been plagued by Eclipse often running, or waiting to run JPA Java Change Event Handler
Currently I am working on a project that doesnt use JPA, yet these Event Handler still appears.
I have seen varies other SO and forum posts related to this, but I have not found a solution that works.
I have tried removing Dali and any plugins that show when searching for JPA - but the problem still remains. For example, I have removed the following - but the problem remains:
I am using Eclipse Version: Oxygen.1a Release
Try this (It worked for me):
Windows:
cd eclipse_install_directory
mkdir disabled\features && mkdir disabled\plugins
move plugins\org.eclipse.jpt.* disabled\plugins
move features\org.eclipse.jpt.* disabled\features
Linux:
cd eclipse_install_directory
mkdir -p disabled/features && mkdir -p disabled/plugins
mv plugins/org.eclipse.jpt.* disabled/plugins
mv features/org.eclipse.jpt.* disabled/features
