Re: openjdk-6 build failure on m68k - problem with fork="true" ant javac target

[Xerxes Rånby <xerxes@zafena.se>]

made a new testcase for ant this morning and found the early ant exit 
bug in the exec ant target as well.

testing ant exec target with this simple testcase:

<?xml version="1.0" encoding="UTF-8"?>
<project name="antexectest" default="build">
   <target name="build">
       <echo message="running exec with the executable='w'"/>
       <exec executable="w"/>
       <echo message="done"/>
   </target>
</project>


============================================== output from debian m68k (fail)

xerxes@aranym-m68k:~/antexectest$ ant
Buildfile: build.xml

build:
    [echo] running exec with the executable='w'
    [exec]  11:21:51 up 46 days, 22:19,  2 users,  load average: 0.87, 0.39, 0.21
xerxes@aranym-m68k:~/antexectest$


============================================== output from ubuntu x86 (success)

xerxes@labb:~/antexectest$ ant
Buildfile: build.xml

build:
    [echo] running exec with the executable='w'
    [exec]  11:18:55 up 76 days,  2:06,  2 users,  load average: 0,46, 0,20, 0,15
    [exec] USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
    [exec] xerxes   pts/0    192.168.1.25     30Oct08  1.00s  1.13s  0.86s /usr/bin/java -
    [exec] xerxes   pts/1    :1.0             19Sep08 46days  4days 19:27m gnome-terminal
    [echo] done

BUILD SUCCESSFUL
Total time: 0 seconds
