Comment 5 jiri vanek 2015-11-05 12:22:59 UTC

So. Tehre is an bug  in this jnlp file (please always provide jnlp fiel when there is jnnlp fiel involved)

<application-desc main-class=" com.main.Main">

It is very wrong.  The class " com.main.Main" do not exists, so ITW is right about it.

But "com.main.Main" class do exists.

So if you fix downloaded file (remove leading space before com)  you will be able to lunch this app as it is.


This is old knownbug, but for security reasons this behaviour will not be fixed.

Authors of this jnlp file MUST fix it (== provide VALID main class) 


For future TIW I will probably add warning about sapce in main class and/or runtime argument to fix it. But it can not be made as default.
