High Five Adding new script and diagnostic.getSource() Null

[uchihasv]

Hello i try add some missing scripts like Mobs AI, and i put in scripts/ai/others/new/new.java

And i use correct imports for this and methods like others, but when loading i get NPE:

Code: [Select]

Failed to execute script list!
java.lang.NullPointerException: Cannot invoke "javax.tools.JavaFileObject.getName()" because the return value of "javax.tools.Diagnostic.getSource()" is null
at org.l2jmobius.gameserver.scripting.java.JavaExecutionContext.executeScripts(JavaExecutionContext.java:166)

Java Execution Context:

Code: [Select]

out.println("-----------------------");
out.println("Compilation diagnostics");
out.println("-----------------------");
for (Diagnostic<? extends JavaFileObject> diagnostic : compilationDiagnostics.getDiagnostics())
{
out.println("\t" + diagnostic.getKind() + ": " + diagnostic.getSource().getName() + ", Line " + diagnostic.getLineNumber() + ", Column " + diagnostic.getColumnNumber());
out.println("\t\tcode: " + diagnostic.getCode());
out.println("\t\tmessage: " + diagnostic.getMessage(null));
}
I think debugger try get source line and name to output, but in diagnostic.getSource() get Null instead of script code, why?

I try search about this in StackOverflow and some Java users say it's maybe can be if java run in JRE instead of JDK, but i use Bellsoft OpenJDK(from l2jmobius bitbucket readme.txt).

Has anyone had problems with this?

I remember that I faced this problem before and the temporary solution was to comment out this line, but maybe there is another normal solution?

My temp fix for this problem is add some checking to null in diagnostic.getSource():

Code: [Select]

String diagnosticSourceName = (diagnostic.getSource() != null)? diagnostic.getSource().getName() : "";
