JDK-6499219 - SIGXFSZ kills VM
Description
We ignore SIGPIPE and SIGXFSZ since their default action is to terminate the VM. 

But on ppc64 (both Linux and AIX) and s390 handling of SIGXFSZ was missing so far, exposing us to JDK-6499219.

[~shade] Unfortunately [~stuefe] isn't an jdk8u updates project Reviewer[1]. I've reviewed it now so as to cover that base too: https://mail.openjdk.java.net/pipermail/jdk8u-dev/2021-April/013741.html Perhaps consider proposing [~stuefe] for 8u Reviewer? I believe we ran into this problem before. [1] https://openjdk.java.net/census#stuefe

Fix Request (8u) This fixes the corner case in PPC support. Patch does not apply cleanly to 8u and requires minor adaptations. Passes the reproducer from this issue now. 8u RFR (acked by tstuefe): https://mail.openjdk.java.net/pipermail/jdk8u-dev/2021-April/013670.html

Fix Request: Important to fix because: exceeding file io limits may kill the VM on ppc and s390 Nature of fix: handle (ignore) SIGXFSZ like other platforms Low risk because: Patch is trivial. Applies cleanly: No, since "8252324: Signal related code should be shared among POSIX platforms" shuffled a lot of coding around.
