Thanks Dmitry!

Should I send a changeset to you for JDK 9? or JDK 10?

Yasumasa,

Changes looks good to me. I'll sponsor the push. -Dmitry On 2017-02-10 17:15, Yasumasa Suenaga wrote: Hi all,

In modern Linux e.g. Fedora 25, executables are built as DSO for security [1]. java command in OpenJDK which is provided by distribution is also DSO. However, SA does not work with DSO executables. I uploaded a webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8173941/webrev.01/ I discussed about this issue with Andrew in mail thread [2], and this webrev has been reviewed by him. We need one or more reviewer. Could you review it?

Currently, OpenJDK 8 in Fedora 25 is built as DSO. So I want to contribute this patch to JDK 8 or later release. I cannot access JPRT. So I need a sponsor.
