# Build within Portage using JDK 11+ (also presumably 9+) fails during
# src_configure:
#	configure: error: sun.security.util.SecurityConstants not found.
#
# When upstream's build instructions are executed outside Portage using
# JDK 11+, ./configure also fails, though a different error pops up:
#	configure: error: sun.applet.AppletImageRef not found.
#
# If even the upstream build instructions fail outside Portage with JDK 11+,
# then it is very unlikely that the build issue within Portage is fixable.
# The upstream has moved forward to development of 2.0.0 and 3.0.0 versions,
# so they might no longer be interested in fixing the legacy 1.x versions.
#
# The 'sun.applet.AppletImageRef not found' issue has been reported to
# FreeBSD <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248197#c2>,
# and some efforts there to fix the issue were unsuccessful.  They seem
# to have ended up with restricting Java version to 8
# <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244976#c17>.
#
# Thus, the build VM version is restricted to 1.8 here.
