------------------------------------------
thanks for catching this [~tedyu] - may I ask which automated tool you're using
to find these implementation issues?
> Potential null dereference in PreparedScript#enableFunctionRecompile
> --------------------------------------------------------------------
>
> Key: SYSTEMML-1769
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1769
> Project: SystemML
> Issue Type: Bug
> Reporter: Ted Yu
> Priority: Minor
>
> Here is related code:
> {code}
> FunctionCallGraph fgraph = _prog.getProgramBlocks().isEmpty() ? null :
> new
> FunctionCallGraph(_prog.getProgramBlocks().get(0).getStatementBlock().getDMLProg());
> ...
> if( !fgraph.isRecursiveFunction(fkey) ) {
> {code}
> The assignment indicates that fgraph may be null.
> In the for loop, we should check fgraph against null before dereferencing.
