Comments
The same typo is presented in JDK7. So, seems we need to get it backported to jdk7 as well.

Haven't seen the critical request template when was looking at the bug first time. No objections from SQE to take the safe fix to PSU16_03.

What is a justification to take it in PSU? Do we need backports?

Critical Request Template - Justification : Test fails because of typo in output that has been fixed in JDK 9. The reason to do a critical request is that it is completely safe, and that typos look bad. - Risk Analysis : None, fixing typo - Webrev : http://hg.openjdk.java.net/jdk8u/jdk8u-dev/hotspot/rev/79351ea143ee - Testing (done/to-be-done) :Run the test that failed before - Back ports (done/to-be-done) : Done - Fix For Release : JDK 8 PSU

This looks very much like JDK-8076995, but that was fixed in b02. Fairoz, please investigate
