This is due to the openjdk-NN-jre and openjdk-NN-jre-headless
prerm maintscripts removing the alternatives during «deconfigure»,
which can cause the lose of manual state during upgrades. This is
documented in the update-alternatives man page.

This should be fixed in all current openjdk versions, just reassigning
to the one affected by this report, and leaving the rest to the
maintainer.
