Fix Request (11u) Same reason as for 15u.

Fix Request (15u) This resolves a compilation warning. Patch applies cleanly to 15u, passes Linux x86_64 Zero bootcycle build.

Partially fixed in 16 and 15u with JDK-8254144. Needs the full fix in 11u and 8u.

Please note based on the JDK 12 schedule details, changing the fix version here to tbd. Please update if required. Thanks. ( http://openjdk.java.net/projects/jdk/12/ )

Yeah, I'll try and get this in the newer versions.

Hi [~andrew], Request your help. (Please note based on JDK 12 schedule I am checking possible deferral candidates of JDK 12 hotspot/compiler tasks - http://openjdk.java.net/projects/jdk/12/) Are you planning 8197981 fix to be in JDK 12 also? (else you may please change the 'Fix Version' in JBS to 'tbd' for now and update with a correct version later when available). Thanks.

Yes. It's actually already in OpenJDK 7: http://hg.openjdk.java.net/jdk7u/jdk7u/hotspot/rev/ce3abb5889fb But needs to be forward-ported to 8u, 10u & 11. I'll do that as soon as I have a setup to build OpenJDK 11.

Hi @Andrew Hughes, Request help information here. I believe you are planning to submit this 8197981 fix review and targeting the same changeset for JDK 11 itself. But otherwise if in case you are not planning this one for JDK 11, please change the 'Fix Version' to tbd_feature / tbd_update. Thank you. (JDK 11 Schedule - http://openjdk.java.net/projects/jdk/11/)

That looks good to me.

Yes, the fix I have is: https://icedtea.classpath.org/hg/release/icedtea7-forest-2.6/hotspot/rev/ce3abb5889fb

Same code is in os_bsd_zero.cpp.
