http://issues.apache.org/bugzilla/show_bug.cgi?id=32853 Summary: <java> with fork=true and failOnError=false shows exception stack trace on timeout Product: Ant Version: 1.6.2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P3 Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Overview: - In Ant 1.6.2 and a recent nightly build, the <java> task, with fork="true", failOnError="false" and timeout="4000" (for instance), when the timeout expires, correctly terminates the class specified, shows "Timeout: killed the sub-process", but then also shows an exception stack trace. - In Ant 1.6.1, no exception stack trace was shown, which seems appropriate in this situation. Steps: 1)create file Applet1c.java: public class Applet1c { public static void main(String[] args) { try { Thread.sleep(10000); } catch (InterruptedException e) { } } } 2)create build.xml: <project name="MyProject" default="Applet1c" basedir="."> <target name="Applet1c"> <java classname="Applet1c" classpath="${basedir};${basedir}/.." dir="." error="tmp.txt" failonerror="false" fork="true" timeout="4000"/> </target> </project> 3)run ant: ant Actual output: Buildfile: build.xml Applet1c: [java] Timeout: killed the sub-process [java] at org.apache.tools.ant.taskdefs.Java.fork(Java.java:749) [java] at org.apache.tools.ant.taskdefs.Java.executeJava(Java.java:170) [java] at org.apache.tools.ant.taskdefs.Java.execute(Java.java:83) [java] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:275) [java] at org.apache.tools.ant.Task.perform(Task.java:364) [java] at org.apache.tools.ant.Target.execute(Target.java:341) [java] at org.apache.tools.ant.Target.performTasks(Target.java:369) [java] at org.apache.tools.ant.Project.executeTarget(Project.java:1214) [java] at org.apache.tools.ant.Project.executeTargets(Project.java:1062) [java] at org.apache.tools.ant.Main.runBuild(Main.java:673) [java] at org.apache.tools.ant.Main.startAnt(Main.java:188) [java] at org.apache.tools.ant.launch.Launcher.run(Launcher.java:196) [java] at org.apache.tools.ant.launch.Launcher.main(Launcher.java:55) BUILD SUCCESSFUL Total time: 13 seconds Expected output: Buildfile: build.xml Applet1c: [java] Timeout: killed the sub-process BUILD SUCCESSFUL Total time: 13 seconds Suggested solution: - This change in behavior from Ant 1.6.1 to 1.6.2 seems to be related to the bug fix described in the release notes of Ant 1.6.2: "<java> swallowed the stack trace of exceptions thrown by the executed program if run in the same VM.". - A possible solution would be to change the file org\apache\tools\ant\taskdefs\Java.java (Ant 1.6.2), line 183 and following, as follows: } catch (BuildException e) { if (failOnError) { throw e; } else { if (fork && (!spawn)) { log(e.getMessage(), Project.MSG_ERR); } else { log(e); } return 0; } } catch (Throwable t) { -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
