First script engine call can incorrectly report error as in a builtin,
subsequent identical calls do not
--------------------------------------------------------------------------------------------------------
Key: JRUBY-3113
URL: http://jira.codehaus.org/browse/JRUBY-3113
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.1.5
Environment: Linux clevo 2.6.25.14-69.fc8 #1 SMP Mon Aug 4 14:20:24
EDT 2008 i686 i686 i386 GNU/Linux
Reporter: David Campbell
Priority: Minor
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:
[EMAIL PROTECTED] ~]$ javac -classpath .:jruby.jar:jruby-engine.jar jruby2.java
[EMAIL PROTECTED] ~]$ 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
