Don’t forget to tell us about your stack!

OS: Win 10

Getting a weird error here, no idea what to make of it. Anyone has any ideas?

<cftry>
  
  <cfcatch type="any">

  </cfcatch>
  <cffinally>
    <cfloop query="filesToMerge">
      <cftry>
        <cffile action="delete" file="#filesToMerge.name#">
        <cfcatch>
        </cfcatch>
      </cftry>
    </cfloop>
  </cffinally>
</cftry>

This code does not produce the NullPointerException:

<cftry>
  
  <cfcatch type="any">

  </cfcatch>
  <cffinally>
    <cfloop collection="#filesToMerges#" index="index" item="filesToMerge">
      <cftry>
        <cffile action="delete" file="#filesToMerge.name#">
        <cfcatch>
        </cfcatch>
      </cftry>
    </cfloop>
  </cffinally>
</cftry>

Somehow seems to be connected with the loop type being query maybe?

please always post the top few lines of a stacktrace with a NPE or any other crash,

Ok, I will remember that for the future.

Its looks like NPE throws while using block ( like cfsavecontent, cftransaction, cfdocument) in cffinally block, which has another try-catch.
