Subject [jira] [Commented] (APEXCORE-593) apex cli get-app-package-info could not retrieve properties defined in properties.xml
Date Tue, 14 Mar 2017 09:09:41 GMT

    [ https://issues.apache.org/jira/browse/APEXCORE-593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15923840#comment-15923840
] 

Vikram Patil commented on APEXCORE-593:
---------------------------------------

Following steps are executed when get-app-package-info is called

1) DAG is generated using operators and augmenting it with Operators from Modules
2) While the module is flattened, populateDAG on the module is called and sometimes this custom
made may expect libraries from properties.xml. But these properties were not set correctly
during this operation. When any method is invoked on unavailable properties, NullPointerException
is thrown leading setting DAG filed in output json to null and setting errorStackTrace with
NullPointerException stack trace.
3) The fix was provided to ensure that properties are available when the module is flattened.
This operation was happening at the time of launching an application so it doesn't cause much
of a issue
