13,247 PointsError: JavaREPL in workspace terminates after first statement
Are there any tips to get JavaREPL working in the Treehouse workspace?
When I try to write a basic Java statement like String name = "Dan";
, the REPL just says "Terminating...".
Here's the full I/O:
treehouse:~/workspace$ java-repl
Welcome to JavaREPL version 272 (Java HotSpot(TM) 64-Bit
Server VM, Java 1.8.0_20)
Type expression to evaluate, :help for more options or p
ress tab to auto-complete.
java> String name = "Dan";
Terminating...
treehouse:~/workspace$
Updates:
- I am mainly running on Chrome and getting these errors. I also tried a few times on Internet Explorer and got the same "Terminating..." error.
- 2014-12-20: I tried creating a new Java workspace, which had the same error. I've sent a message to support.
- 2014-12-21: I tried creating another new workspace that also didn't work. The first two times executing
java-repl
in the console, I wasn't even able to connect. But, at least I was able to connect after that. Then, it quickly terminated for the first Java statement that I entered. Then, I tried deleting all the workspaces, and creating a new one, which also didn't work when executing any Java statement. It appears that executing:help
in the JavaREPL in the workspace works. -
Here's another one of the errors I saw. But, at least this one went away the third time that I tried running
java-repl
.treehouse:~/workspace$ java-repl Welcome to JavaREPL version 272 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_20) Type expression to evaluate, :help for more options or press tab to auto-complete. ERROR: Could not start REPL instance at http://localhost:59049 Terminating... treehouse:~/workspace$
2014-12-21: A new workspace on Firefox presented the same problem.
2015-01-09: Re-using the last Java workspace I made last year, the same error still occurs.

42,016 PointsCraig mentions that it crashes from time to time. have you tried reopening your workspace and restarting the repl? Does this happen every single time?
Stone Preston
42,016 Pointswhat browser are you using? I just tried in chrome and it worked fine so you might try chrome if you arent using that already
Danial Goodwin
13,247 PointsI'm using Chrome now, but I'll try fully restarting it and let you know. And, perhaps even try IE after I get the pre-loaded dust off of it.
Stone Preston
42,016 Pointshmm strange. I definitely would have thought recreating the workspace would have fixed it. if you still cant figure it out I would contact support. could be an issue with your account or something. pretty weird though. all the things you said you have tried probably should have had some degree of success, and I tried on mine and it worked so its not like its a site wide issue or anything. not too sure whats up
Danial Goodwin
13,247 PointsOkay, I'll report this possible bug to support. Fully restarting Chrome didn't help. Using Internet Explorer still shows the same "Terminating..." error for the first code entered.
Stone Preston
42,016 Pointsyeah something strange is going on. I just tried the same exact code again and it worked for me, so its not like its invalid syntax or anything like that.

13,247 PointsThank you for your help. Maybe a geo-server is just down temporarily or has a bad copy. I'll update if I learn anything new from more testing or support.
Stone Preston
42,016 Pointsyeah it seems like it could be an issue with the server your workspace is hosted on or something like that. good luck

Treehouse TeacherHey Daniel,
Can you try creating a new workspace? Seems like something is wrong and that specific workspace instance is running out of memory, for some reason.
Let me know if that doesn't work and I will escalate the problem to our developers.
Sorry for the frustration!
Danial Goodwin
13,247 PointsOkay, I've just tried creating a new workspace. Unfortunately, the same problem is still occurring. Also, I've updated the the origin post with a few more details on what I have tried so far.

13,247 PointsIt closes every time the first line of code is entered. I've tried restarting REPL a few times and I've created a new Java workspace to try it in with the same "Terminating..." error. The code I've tried has just been various simple String and int assignments and just
!true
closes REPL also.
