Bug#922720: ca-certificates-java: update-ca-certificates fails with bashism in jks-keystore

[Steven Ihde]

Package: ca-certificates-java
Version: 20170929~deb9u1
Severity: important

Dear Maintainer,

After upgrading to Debian 9.8 today, the following error results
whenever I run update-ca-certificates:

------
$ sudo update-ca-certificates
Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...

/etc/ca-certificates/update.d/jks-keystore: 56: [: amd64: unexpected operator
done.
done.
------

This appears to be due to a bashism introduced by the fix for 874276:

-------
$ checkbashisms /etc/ca-certificates/update.d/jks-keystore
possible bashism in /etc/ca-certificates/update.d/jks-keystore line 56 (should be 'b = a'):
    if [ "$arch" == "armhf" ]; then
-------

Thanks,

Steve
