Alan,

> Can you summarize how this comes about (given the locking on "locks").
Malicious intent or ignorant mis-use by code outside of the FileHandler can
turn the FileHandler into a victim of that misuse.

public static void main(String[] args) throws Exception {
Path p = Files.createTempFile("test", "test");
try (FileChannel pathogen = FileChannel.open(p, CREATE, WRITE)) {
FileLock lck = pathogen.lock();
System.out.println(lck);
try (FileChannel fileHandler = FileChannel.open(p, WRITE, APPEND)) {
FileLock fhl = fileHandler.lock();
System.out.println(fhl);
}
} finally {
Files.deleteIfExists(p);
}
}
