Hello,

The bug is really straight-forward to reproduce:

• edit (or create, if the file hasn't been created yet) the jira-config.properties file
• after any parameter, like this one:

  jira.importid.prefix=unconfigured
  jira.websudo.timeout=10
  

  So, in the code above, pasting a space character after the first parameter, JIRA works normally. However, putting a space after the second one (10), JIRA will not allow users to login, and throws this stacktrace on the screen:

  java.lang.RuntimeException: org.apache.jasper.JasperException: java.lang.NumberFormatException: For input string: "10 "
  

The workaround is remove the space makes JIRA work normally. Apparently, JIRA is having a hard time figuring out spaces after non-string parameters.

I hope this was all the info necessary to troubleshoot this.

Cheers
Thiago Prisco
