[ https://issues.jboss.org/browse/JBIDE-23312?page=com.atlassian.jira.plugi... ] Viacheslav Kabanovich commented on JBIDE-23312: ----------------------------------------------- I noticed that when we set a value to a preference store, we rely on Eclipse saving it automatically. Maybe that is not safe. This change in SSLCertificatesPreference may help. {code} private void saveItemsToPreference(List<Item> items) { StringBuilder sb = new StringBuilder(); items.stream().forEach(i->sb.append(i.toPreferenceValue())); getPreferenceStore().setValue(ALLOWED_CERTIFICATES, sb.toString()); if(getPreferenceStore() instanceof IPersistentPreferenceStore) { try { ((IPersistentPreferenceStore)getPreferenceStore()).save(); } catch (IOException e) { ///ignore } } } {code} [~jeffmaury], if you reproduce the issue, please try it. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
