Lockout recovery process not working. Log says could not load main class

[cquad]

  Hello.

  I recently upgraded from version 5.14.2 to version 7.6. It went smoothly and everything was working.

  Then, over the weekend the JVM was restarted and bitbucket wasn't running. I noticed that I forgot to set it up to start as a service, so I did that. After restarting again, though, I couldn't log in, my credentials were not working anymore. 

  So I followed the lockout recovery process and modified _start_webapp.sh and included the JVM_SUPPORT_RECOMMENDED_ARGS="-Datlassian.recovery.password=temporarypassword" property.

  I remember doing this before, and it worked. But this time, it's not working. This is what I see in the log: 

Error: Could not find or load main class =-Datlassian.recovery.password=temporarypassword

  Any ideas what I should do? Maybe some problem with my Java settings?
