JRebel - Trial Reset

  1. %HOMEDRIVE%%HOMEPATH%\.jrebel
  2. delete the file
    jrebel.pref and jrebel.lic
  3. and create instead a folder with the name
  4. start Java NetBeans (Eclipse, IntelliJ) or what ever you're using jrebel on.
    Now jrebel should complain:

    Press Ok
  5. remove/rename the folder
...and ya are done.

Next time you start NetBeans you're ready to sign in for a new 14-days jrebel trial.

Tested on NB 8.1 with Jrebel 7.0.7.

Anyway that stack dump tells much about what to look for in the Java Decompilier

Btw a glace on jrebel,jar in JD (Jave Decompiler) shows that this cryptic '' tries some ".get("evalString", null)" on the file and gets 'surprised' by some unexpected exception.
