start-jira.bat shows logo but does not start JIRA

DJX

I am transplanting my existing JIRA instance - and when I run the start-jira.bat it shows me the logo as if it's starting, but then does nothing.

It shows this:

\JIRA\bin>start-jira.bat

To run JIRA in the foreground, start the server with start-jira.bat /fg
                .....
          .... .NMMMD.  ...
        .8MMM.  $MMN,..~MMMO.
        .?MMM.         .MMM?.

     OMMMMZ.           .,NMMMN~
     .IMMMMMM. .NMMMN. .MMMMMN,
       ,MMMMMM$..3MD..ZMMMMMM.
        =NMMMMMM,. .,MMMMMMD.
         .MMMMMMMM8MMMMMMM,
           .ONMMMMMMMMMMZ.
             ,NMMMMMMM8.
            .:,.$MMMMMMM
          .IMMMM..NMMMMMD.
         .8MMMMM:  :NMMMMN.
         .MMMMMM.   .MMMMM~.
         .MMMMMN    .MMMMM?.

Any suggestions? I'm sure I'm missing something simple - and I'm sure I'll be told I'm better off with a fresh install, but I'd like to avoid that.

Edit:

I manually tried starting the JAR file with:
java -verbose -jar bootstrap.jar

And I get a little more information:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

Thanks for the advice. I never got around to trying this. I found it less painful to just do a re-install and configure it that way. Hopefully in the future there will actually be error messages to let users know what the problem is.
