...

Sounds like an OpenJDK aarch64 backend issue:

https://bugs.openjdk.java.net/browse/JDK-8153172

Linked patch is already in current sources.

And does their test case succeed or fail on non-LSE systems? -- You are receiving this mail because: You are on the CC list for the bug.

Also seen with Bazel 0.24 with SLE12 SP4.

As workarounds, I will send SRs to make use of openjdk 11/12 for bazel0.2x on aarch64, as only openjdk 1.8.0 is affected, so far.

Workarounds for Bazel 0.24 0.25 0.26: https://build.opensuse.org/request/show/717885 https://build.opensuse.org/request/show/717886 https://build.opensuse.org/request/show/717887 I think Bazel 0.19 is too old to use java 11/12. -- You are receiving this mail because: You are on the CC list for the bug.
