New issue 681 by [email protected]: ComputationException due to
StackOverflowError during injection is hard to track down
http://code.google.com/p/google-guice/issues/detail?id=681
When using Guice on Android, it's relatively easy to construct dependency
chains that overflow the available stack. In my testing I was able to do
it with a chain of length seven on the Android 2.3 emulator (with similar
results on Android 2.2 devices as well).
When this happens, it can be extraordinarily difficult to fix the problem
because the error message does not include sufficient information to know
what Guice was attempting to construct at the time. For example, see the
following for a typical example:

We can see that there are 12 ComputationExceptions, but we can't see what
type was being computed at the time.
We can use the debugger (ala
http://code.google.com/p/roboguice/wiki/ComputationExceptionStackOverflow )
to figure out the types, but this process would be significantly easier if
the ComputationException message included the type key that was being
generated.
