Description
final boolean isInvalid() {
if (status == null) {
status = (this.path.indexOf('\u0000') < 0) ? PathStatus.CHECKED
: PathStatus.INVALID;
}
return status == PathStatus.INVALID;
}
If the reads to "status" are reordered and another thread writes to "status", the return value can be wrong.
Reading "status" to a local variable fixes the issue.
