Problem Description:

If I wrap cfsavecontent around a call to capture the output and that call outputs some text and then raises an exception.  cfsavecontent fails to capture the next that was output prior to the exception and instead captures nothing.  

Steps to Reproduce:

try {
    cfsavecontent( variable="out" ) {
      writeOutput( 'I like spam' )
      throw( 'boom' )
    }
} catch( any e ) {
  // handle error
} finally {
  writedump( out )
}

Actual Result:

Variable OUT is undefined

Expected Result:

The out variable should exist and contain the contents of the buffer that was output prior to the exception.  

Any Workarounds:

I found this hacky workaround where I prevent the error from hitting the cfsavecontent and then rethrow it later after capturing the output.

cfsavecontent( variable="out" ) {
    try {
      writeOutput( 'I like spam' )
      throw( 'boom' )
    } catch( any e ) {
        thisFailure = e;
    }
}

writedump( out )

// Rethrow
if( !isNull( thisFailure ) ) {
    throw( thisFailure );
}

ColdFusion's behavior matches Lucee Server and I have created this ticket for Lucee to address as well. https://luceeserver.atlassian.net/browse/LDEV-2670
