[jbosstools-issues] [JBoss JIRA] (JBDS-3152) Cheatsheet crashes silently when they need to open files

[Radim Hopp (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-3152?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009739#comment-13009739 ] 

Radim Hopp commented on JBDS-3152:
