http.HttpUtil - RSA premaster secret error

Dear users,

has anybody the same problem?


  • raspberry 2
  • java version “1.8.0” Java™ SE Runtime Environment (build 1.8.0-b132)
  • openhab 2 , HTTP Binding, binding-http - 1.9.0.b4

I thing that has something to do with java.

Can anybody help?


Dear users,
unfortunately it seems nobody has this error. Mabey the reason is a wrong java version??

My question is: Can somebody can give the correct setup to run openhab 2 on raspberry pi 2 with wheezy?

Which java is necessary on rpi2 and wheezy. Please send me a link or better an installation manual.


Dear users,

i’ ve updated java 8 - now it works. I’m not sure if this was the reason.

For other people stumbling across this, if you want to use OpenJDK you need to add either the JCE from Oracle or from see

(And if you get this on freebsd, you also need to set your JAVA_HOME variable, as otherwise it is not set correctly by openhab, at least on 2.0)
