SIGSEGV (core dump) java -Xmx64m -jar $JAR -storepass "$storepass"

[Jun Aruga]

## Environment

OS version: Ubuntu arm64-bionic
  I am using below ubuntu container.
  https://hub.docker.com/r/multiarch/ubuntu-debootstrap/tags/
ca-certificates-java: 20180516ubuntu1~18.04.1

```
$ uname -a
Linux 4e7245866a0e 4.15.0-1026-gcp #27~16.04.1-Ubuntu SMP Fri Dec 7 09:59:47 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux
```

## How to reproduce

I created reproducer script.
https://github.com/junaruga/ubuntu-arm-java-sigsegv/blob/master/.travis.yml
The actual result. You can see the core dump here.
https://travis-ci.org/junaruga/ubuntu-arm-java-sigsegv/builds/501915248#L469-L492

```
$ git clone https://github.com/junaruga/ubuntu-arm-java-sigsegv.git
``

Then run Travis CI on your repository,

or run below commands

```
$ docker run --rm --privileged multiarch/qemu-user-static:register --reset
$ docker build --rm -t sample -f Dockerfile-arm64 .
```

or run below commands on your ARM (arm64) environment

```
# apt-get update && apt-get install -y ca-certificates-java
```

Below result is shown randomly with around 30%.
When trying 3 times, succeeded 2 times, failed 1 time on my impression.

Status changed to 'Confirmed' because the bug affects multiple users.

Unable to reproduce using the docker script provided.
The issue affects qemu, rather than ca-certificates-java
