Ted Yu created SYSTEMML-1769: -------------------------------- Summary: 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
