Bug#829008: update-java-alternatives always switches back to default

[Paul Draper]

Package: java-common
Severity: minor
Tags: patch
Version: 0.51

update-java-alternatives briefly switches back to the default Java version.
This can cause programs to fail during this period of time.

This should be an idempotent operation, as it is for update-alternatives.

See the patch below. I presume that do_auto was at one time important for
something, though I have no idea what it was.
