I have a java class running as a task (as a plugin in an Java CMS) which used Quartz. I am now moving it out of the CMS and into a Spring Boot (v1.0.2) project and am using @Scheduled annotation.
The problem i that the ProcessBuilder reports missing executable file, but a File().exist() return true.
It is the same Java version OpenJDK 7, same Application Container (Tomcat 7), on FreeBSD 9.2.
The testing code is a follow:
package test;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;
@Service
public class SchedulerTest {
@Scheduled(fixedDelay=1800000, initialDelay=5000)
public void test() {
if ((new File("/usr/local/bin/exiftool")).exists()) {
System.out.println("Found exiftool");
}
else {
System.out.println("Did not find exiftool");
}
List<String> args = new ArrayList<String>();
args.add("/usr/local/bin/exiftool");
args.add("-n");
args.add("-S");
args.add("-DateTimeOriginal");
args.add("/image/TEST.JPG");
Process proc = null;
try {
proc = new ProcessBuilder(args).start();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (proc != null) {
System.out.println("ExifTool output: " + proc.getOutputStream());
proc.destroy();
}
}
}
The ouput is:
2014-04-28 12:30:49.471 INFO 22473 --- [ost-startStop-7] o.s.boot.SpringApplication : Started application in 10.997 seconds (JVM running for 4022.804)

What may be the problem? My guessing is the move from Quartz to @Scheduled. I have also tried to create cutsom bean and set the thread pool to 2, without any luck.
