Problems with telnet task during an ant migration
We are in a migration from ant 1.6.2 to 1.8.0 and are encountering troubles
using telnet task :
<?xml version="1.0" encoding="ISO-8859-1"?>
<project name="testtelnet" default="compile" basedir=".">
<target name="telnet">
<telnet userid="XXX" password="YYY" server="ZZZ">
<read>></read>
<write>ls</write>
<read string="/home/bob"/>
</telnet>
</target>
</project>
throws an OOM
Distant server is Sun OS 5.8 (Solaris 8)
This simple script is OK with 1.6.2, but not with 1.8.0 :
java.lang.OutOfMemoryError: Java heap space
[java] at java.util.Arrays.copyOf(Arrays.java:2882)
[java] at
java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100)

[java] at
org.apache.tools.ant.taskdefs.optional.net.TelnetTask.execute(TelnetTask.java:109)
We replaced TelnetTask with the old one from 1.6.2 as a workaround.
After a quick look to the source, it seems that the change
http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/optional/net/TelnetTask.java?r1=677886&r2=677887&is
wrong, especially the replacement of a String.indexOf by a
String.substring
Greetings

Maybe it was the wrong mailing list. Should I send a mail to the dev mailing
list or file a bug directly?
