Public bug reported:
OBSERVED BEHAVIOR:
Matlab stays in busy state when using some functions like "plot" or even
"exit", while executing through a ssh tunnel with X11 forwarding.
REPRODUCE THE BUG:
You need matlab (my version is R2017a) to reproduce the bug. I suspect
any version >= 2014b would reproduce the bug (HG2 framework), and maybe
any version.
1. Connect to self (or from other machine) with X forwarding:
$ ssh -X user@localhost
2. Launch matlab
$ matlab &
3. Plot something
>> plot(1,1)
ADDITIONAL INFORMATION
- Normal behavior would be appearance of a new window and a single point at
position (1,1).
- No ressources seem to be used.
- Opening a figure alone is possible. (>> figure). Opening other windows from
the graphical user interface is possible
- Opening Matlab without the java machine seems to work, but matlab relies
heavily on java. At least "exit" which doesn't work with java, works without
java.
- Providing Matlab with open-jdk version 1.8.0_144 didn't change anything.
- This used to work perfectly for as long as I have been using Ubuntu (since
2012).
