[jopr-issues] [JBoss JIRA] Commented: (JOPR-88) TC5 not discovered due to NPE

[Jay Shaughnessy (JIRA)]

    [ https://jira.jboss.org/jira/browse/JOPR-88?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12456802#action_12456802 ] 

Jay Shaughnessy commented on JOPR-88:
-------------------------------------


I think this is just a coding mistake, instead of 

    if (null == cwdPath) 

it should be

    if (null == result) 


The logic around determining the install dir this way was due to the impl of EWS CR1, where catalina.home was being defined as a relative path making things difficult.   This is rectified in CR2.
