Incorporated Stapler 1.222 to pick up fixes

Fixed a bug in bytecode-compatibility-transformer where class file
format prior to 1.49 cannot have the ldc instruction pointing to a class
constant.

[JENKINS-20074] When displaying an uncaught exception, if we are unable to write the content, just do nothing.

Integrating the stapler fix.

Consult Descriptor.newInstance() even when proccessing is in the middle
of JSON tree.
(cherry picked from commit d15c1550)

[FIXED JENKINS-18836][FIXED JENKINS-18879][FIXED JENKINS-19619] Upgrade trilead-ssh to version with the fix

This reverts commit d15c1550.

Consult Descriptor.newInstance() even when proccessing is in the middle
of JSON tree.

[JENKINS-19192] Using JNR 3.0.1 which includes JNR-FFI 1.0.7; 1.0.6 has the backported fix for Guava #1505, the root cause.
So this upgrade ought to prevent a recurrence of the issue in case some other code refers to JNR from the CLI.
(As yet untested, and we do not especially want to send JNR over the CLI channel anyway for performance reasons.)
