Could not find file to copy in ant.copy although file exists - unix

Question

I am calling ant.copy in a groovy script:
ant.copy(file:jdbcDriverPath, toFile:destJDBCJarFile,overwrite:true)
The call is failing with the exception below, although the file exists under the path.
The same code launched on Windows works. When launched on Unix with java jdk1.7.0_51, it is failing.
Machine details on Unix:
$ uname -a
SunOS 5.10 Generic_142910-17 i86pc i386 i86pc
$ isainfo -kv
64-bit amd64 kernel modules
Any ideas?
Exception in thread "main" : Warning: Could not find file /data/apps/packages/temp/jconn3-6.05_26312.jar to copy.

The copy task is failing while running the below snippet (from the source of Ant 1.9.4):
private void copySingleFile() {
// deal with the single file
if (file != null) {
if (file.exists()) {
if (destFile == null) {
destFile = new File(destDir, file.getName());
}
if (forceOverwrite || !destFile.exists()
|| (file.lastModified() - granularity
> destFile.lastModified())) {
fileCopyMap.put(file.getAbsolutePath(),
new String[] {destFile.getAbsolutePath()});
} else {
log(file + " omitted as " + destFile
+ " is up to date.", Project.MSG_VERBOSE);
}
} else {
String message = "Warning: Could not find file "
+ file.getAbsolutePath() + " to copy.";
if (!failonerror) {
if (!quiet) {
log(message, Project.MSG_ERR);
}
} else {
throw new BuildException(message);
}
}
}
}
From the message string, there is an additional space in the filename /data/apps/packages/temp/jconn3-6.05_26312.jar.
This can also be reproduced using the following:
java.io.File file = new java.io.File("some_file_that_exists ");
System.out.println(file.exists()); // true on Windows, false on SunOS
The file.exists() returns true on Windows (automatically trimmed), but false on SunOS.
