[jbosstools-issues] [JBoss JIRA] (JBIDE-10703) Follow common pattern in bundle activator classes

Follow common pattern in bundle activator classes ------------------------------------------------- Key: JBIDE-10703 URL: https://issues.jboss.org/browse/JBIDE-10703 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: common/jst/core Affects Versions: 3.3.0.M5 Reporter: Viacheslav Kabanovich Assignee: Viacheslav Kabanovich Priority: Minor Fix For: LATER 1. Static instance of plugin implementation should be assigned in constructor, not in start() method. 2. Static instance of plugin implementation should not be set to null in method stop() as it may cause logging NullPointerException at Eclipse shutdown (we already had such issues, mostly reproduced in automatic tests). 3. Extend BaseUIPlugin in plugins that depend on common module.
