Fix potential NPE on exception path

Findbug reported NP_NULL_ON_SOME_PATH_EXCEPTION, Priority: Normal
ComputerLauncherTest failed with LANG=ja_JP. It seems to use invalid expect.
If the output of 'java -version' is 'java version "1.7.0_05" ', then the expect should be 1.7.0 not 1.7

[JENKINS-17332] Allow sign up with username that exists because of SCM commit.
[FIXED JENKINS-19135] Permit a user to configure an axis with no values without throwing exceptions.
The project cannot be usefully built in this case but at least they can go back and reconfigure it.
Also fixing Layouter.Column to not throw NoSuchElementException (in violation of Iterator contract)
and thus break project overview when there is an empty Axis in the trivial list (due to an unintentional IndexOutOfBoundsException).
[FIXED JENKINS-19192] LoginCommand failed on Windows after introduction of JNR.
Root cause of class loading error (on jnr.ffi.util.ref.internal.Finalizer$ShutDown) still unclear,
but easy fix is to simplify ClientAuthenticationCache.save to use FilePath.chmod,
which at least for now relies on hudson.util.jna.GNUCLibrary rather than JNR.
