[SOLVED] java.io.IOException: Unexpected EOF When Jenkins slave tries an SVN checkout

I am trying to setup a Jenkins slave on a separate Windows 10 machine. The master runs on windows 8.1. slave.jar is being executed with a command on the master. I do this using winrs: winrs -r:192.168.xxx.xxx -u:MyUserName -p:MyPassword java -jar C:\JenkinsAgent\slave.jar

I am at the point where executing a test job that solely runs echo Hello World as a batch command succeeds.

When I add modules to be checked out from an Subversion server the test job fails however. I see either one of the following two errors in the log of the test job and it seems rather random when either one pops up.

Error 1:

So this only happens when I try to do a checkout on the slave since simply running echo Hello World works. Manually checking out the repository that I want to check out from the slave machine also works.

I am stuck with this problem since googling on all the info I have turned up empty and I don't know any other way to gather more information about what's actually happening.

Update1: In the general Jenkins log (at Manage Jenkins->System Log->All Jenkins Logs) I'm seeing this error message appearing:

A google search pointed me to https://issues.jenkins-ci.org/browse/JENKINS-19445 and https://issues.jenkins-ci.org/browse/JENKINS-48309. I am not sure if this has anything to do with my problem but people are experiencing partly the same things as I do. The latter is in review and might fix this problem in some later release but that is just a guess.
