Description
I used fastdebug VM for javac and hit next assert:

 6085   Bool    === _  6893  [[ 6086 ]] [lt] !orig=[5819]
# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/phaseX.cpp:952
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (hotspot/src/share/vm/opto/phaseX.cpp:952), pid=17714, tid=40
#  assert(false) failed: modified node is not on IGVN._worklist
#
# JRE version: Java(TM) SE Runtime Environment (9.0) (build 1.9.0-internal-fastdebug-2014_12_29_15_09-b00)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (1.9.0-internal-fastdebug-2014_12_29_15_09-b00 mixed mode solaris-amd64 compressed oops)

It is the same place as in JDK-8053915.

Does not affect 8u since this verification code is present only in jdk9.
