Description
from #jruby:
CaneToad: it seems the first time you invoke the script engine, it can report the error to be in the builtins when it isn't...doesn't happens on subsequent calls to the script engine
headius: hmmm
...
headius: I'd say go ahead and file it
Java code to reproduce:
////////////////////////////////////////////////////////////////////
import javax.script.*;
public class jruby2 {
public static void run(ScriptEngine engine, String msg) {
System.err.println(msg);
try {
engine.eval("a=Hello");
} catch(ScriptException e) {
e.getCause().printStackTrace(System.err);
}
}
public static void main(String [] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("jruby");
run(engine, "------------ first");
run(engine, "------------ second");
}
}
////////////////////////////////////////////////////////////////////
Here's what it gives:
[dcampbel@clevo ~]$ javac -classpath .:jruby.jar:jruby-engine.jar jruby2.java
[dcampbel@clevo ~]$ java -classpath .:jruby.jar:jruby-engine.jar jruby2
------------ first
/builtin/javasupport.rb:49:in `const_missing': uninitialized constant Hello (NameError)
from <unknown>:1
...internal jruby stack elided...
from Module.const_missing(<unknown>:1)
from (unknown).(unknown)(:1)
------------ second
null:1:in `const_missing': uninitialized constant Hello (NameError)
from <unknown>:1
...internal jruby stack elided...
from Module.const_missing(<unknown>:1)
from (unknown).(unknown)(:1)
Notice that the first call reports the error in a builtin, while the second identical call does not
