https://bz.apache.org/bugzilla/show_bug.cgi?id=58478
Bug ID: 58478
Summary: Ant EXEC tasks randomly hangs while executing set of
java based application commands.
Product: Ant
Version: 1.9.6
Hardware: PC
OS: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: Core tasks
Assignee: notifications@ant.apache.org
Reporter: rahulhraut@gmail.com

Ant Script which is failing inconsistently.
I am using a Ant scripts which loads a xml files located at pre-defined paths
into a Java Application (WEB N-Tier Architecture) using Application based
API's. the ant scripts pick the xml files using loop tasks and then fire a
command to load a file. The loading using ant scripts most of the time hang in
between. Sometime it loads all the files. the ratio of success is 1 in every 3
attempts. I am attaching a load file along with this case.

Since this bug was opened ( 2015-10-04 ), the commons-IO which provides
FileUtils.copyFile() had the following Release Notes that could maybe be linked
to this issue. I assume that the user was using Commons IO 2.4 or earlier.
Apache Commons IO Version 2.5
(https://commons.apache.org/proper/commons-io/upgradeto2_5.html)
IO-385: FileUtils.doCopyFile can potentially loop for ever
Exit loop if no data to copy
Apache Commons IO 2.6
(https://commons.apache.org/proper/commons-io/upgradeto2_6.html)
IO-502: Exceptions are suppressed incorrectly when copying files.
Thanks to Christian Schulte.
The user could change his application then the file copy would be done by ANT
instead of the ReportLoader.java on which we have no way to debug (or at least
outside of our scope).
I think this bug could be closed.

Assuming Eugene is right, please reopen if problem still exists and seems to
originate from ant, and not from the command called.

It looks like the problem is with third party code which uses
FileUtils.copyFile(), but the failure occurs after copyFile() is called? in
undisclosed code?

Some additional information which may help.
Almost all the time whenever the Ant build hangs while running (using EXEC) a
command (java code) is after
(ReportLoader.java)
File dtdx20 = new
File(WTProperties.getServerProperties().getProperty("wt.home") +
windchillDirectorySeperator +"loadXMLFiles" + windchillDirectorySeperator+
"standardX20.dtd");
File copiedDtdx20 = new File(tempLocation+"standardX20.dtd");
FileUtils.copyFile(dtdx20, copiedDtdx20);
