Hi,

I encountered another one:

  javac -classpath "/home/arsen/Android/Sdk/platforms/android-Tiramisu/android.jar:." -target 1.7 -source 1.7 -Xlint:d
  eprecation org/gnu/emacs/EmacsContextMenu.java

  make[2]: *** [Makefile:261: org/gnu/emacs/EmacsContextMenu.class] Error 1 shuffle=2758590628

I tried replicating with that shuffle= value, but it seems that I did
not get lucky twice.  However, I believe I have the reason why:

  ~/gnu/emacs-android2 130 $ grep -r --include='*.java' Holder
  java/org/gnu/emacs/EmacsService.java:class Holder<T>
  java/org/gnu/emacs/EmacsService.java:    final Holder<EmacsView> view;
  java/org/gnu/emacs/EmacsService.java:    view = new Holder<EmacsView> ();
  java/org/gnu/emacs/EmacsService.java:    final Holder<ClipboardManager> manager;
  java/org/gnu/emacs/EmacsService.java:    manager = new Holder<ClipboardManager> ();
  java/org/gnu/emacs/EmacsDialog.java:    final Holder<Boolean> rc;
  java/org/gnu/emacs/EmacsDialog.java:    rc = new Holder<Boolean> ();
  java/org/gnu/emacs/EmacsContextMenu.java:    final Holder<Boolean> rc;
  java/org/gnu/emacs/EmacsContextMenu.java:    rc = new Holder<Boolean> ();

There is no dependency between these Holder<T> users and the .java that
provides it:

  ~/gnu/emacs-android2/java$ rm org/gnu/emacs/EmacsDialog.class
  ~/gnu/emacs-android2/java$ make org/gnu/emacs/EmacsDialog.class

The simplest way to fix it is probably to break out Holder<T> into
Holder.java, as that won't require manually bookkeeping the
dependencies.  I attached a patch, which builds on x86_64-pc-linux-gnu.
