SEVERE: IO error -- builtin/javasupport (LoadError)

Ruby JRuby

I am seeing the error below when trying to run jruby 1.2.0 and Rails
2.3.2
application on GlassFish. Any idea why I should see this error? It might
be
some classpath issue but if someone could tell what is that JRuby is
looking
for that is not available will be really helpful.

Pass -d and you should get a better backtrace. That LoadError usually
means something failed to compile.

Ok, so it is ClassCircularityError emitted while compiling
builtin/javasupport.rb.

Well that’s bizarre…I don’t even know how that would happen. Do a
little more investigation and if you can’t make it go away toss it into
a bug.

public enum LexState {
EXPR_BEG, EXPR_END, EXPR_ARG, EXPR_CMDARG, EXPR_ENDARG,
EXPR_MID,
EXPR_FNAME, EXPR_DOT, EXPR_CLASS, EXPR_VALUE
}

Pretty weird. A simple enum is causing this? Not even sure how it
could be circular since I do not know how enums compile down via
javac. Clearly something really weird with classloading?

It is coming from:

Ruby.java:

public void loadFile(String scriptName, InputStream in, boolean wrap) {
IRubyObject self = wrap ? TopSelfFactory.createTopSelf(this) :
getTopSelf();
ThreadContext context = getCurrentContext();
String file = context.getFile();

    try {
        secure(4); /* should alter global state */

        context.setFile(scriptName);
        context.preNodeEval(objectClass, self, scriptName);

  •        parseFile(in, scriptName, null).interpret(this, context,

self,
Block.NULL_BLOCK);*
} catch (JumpException.ReturnJump rj) {
return;
} finally {
context.postNodeEval();
context.setFile(file);
}
}

Problem is jruby runtime can’t get created so nothing works on GlassFish
v3
trunk due to this issue!

Whew…I was worried. So we’re off the hook then? Let us know if you
need anything else.

This appears to be a regression[1] in Felix 1.6.0. Basically, it was
caused
due to the fact that during the classload, felix was trying to introspec
the
inner classes to determine the enclosing class.
