input task fails if 2 inputs redirected from a file

           Summary: input task fails if 2 inputs redirected from a file
           Product: Ant
           Version: 1.5.1
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Core tasks
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


If we create 2 input tasks and then redirect stdin from a file, then the 2nd 
input task will fail.

Procedure to reproduce:
First, create 2 input tasks:
<target name="ema-test">
    <input
        message="input 1"
        addproperty="test.input1"
    />
    <echo message="result is ${test.input1}"/>
    <input
        message="input 2"
        addproperty="test.input2"
    />
    <echo message="result is ${test.input2}"/>
</target>

Then call the target by redirect input from a file:
ant -buildfile build.xml ema-test < input.txt

The content of input.txt is:
      1
      2
      3

Error Message:
ema-test:
input 1
result is 1
input 2
