Message11457

I was pointed to this issue in JyNI context, but it seems to be JyNI-unrelated.
On OSX macOS Sierra 10.12.5 / Oracle Java 1.8.0_131 / Jython 2.7.1 RC2/RC3/Final, using the terminal:

[ERROR] Failed to construct terminal; falling back to unsupported

The issue is known in different context:
https://stackoverflow.com/a/44329833

A suggested workaround is to set the environment variable TERM to a dfifferent value than "xterm-256color".
(Apparrently, newer ncurses displays 256 as 0x100 for better readability.)

This is said to be fixed in recent JLine2. So maybe another update of JLine2 can solve this issue in Jython.
