Bug ID: 64438
Summary: FTP IOException causes NullPointerException
Product: Ant
Version: 1.10.7
Hardware: PC
Status: NEW
Severity: regression
Priority: P2
Component: Optional Tasks
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
ant version: 1.10.7, 1.10.8
regression introduced in commit: e6b44170a8419f01a5ea45b4917f569ca45aafff
When an IOException exception occurs during an FTP session, the catch code may
yield a NullPointerException when the original exception cause is null.
This can be reproduced by trying to connect to a non existing FTP server using
the following snippet.
<ftp server="127.0.0.1" userid="..." password="..." />
Which would yield the following exception stack trace.
Caused by: java.lang.NullPointerException
