Hi,
I've just upgraded from 1.5R4 to 1.7R1 and some scripts that used to compile
now no longer compile.
My code is pretty much as follows:
context.setGeneratingDebug( true );
context.setOptimizationLevel( 0 );
this.script = context.compileReader( reader, fileName, 1, null );
Then I call a function multiple times on the same script, throwing the scope
away after each execution:
Scriptable scope = new ImporterTopLevel();
this.script.exec( context, scope );
Object functionObject = scope.get( functionName, scope );
if ( functionObject instanceof Function )
{
Function function = (Function)functionObject;
function.call( context, scope, null, args );
}
The first question is whether this usage is acceptable. I want to reuse the
compiled code to save perm gen space and compilation time. I need to throw
away the scope between executions to save heap space between function calls.
Some of my scripts don't compile properly any more. The error I get is when I
call compileReader:
java.lang.VerifyError: (class: org/mozilla/javascript/gen/c3, method: _c1
signature:
(Lorg/mozilla/javascript/gen/c3;Lorg/mozilla/javascript/Context;Lorg/mozilla/javascript/Scriptable;Lorg/mozilla/javascript/Scriptable;[Ljava/lang/Object;)Ljava/lang/Object;)

at org.mozilla.javascript.Context.compileReader(Context.java:1202)
at org.mozilla.javascript.Context.compileReader(Context.java:1174)
I've isolated the part of the script that causes the error (attached). If I
remove one of the inner-most try-catch errors, the error disappears. If I
remove the finally section, the error also disappears. I don't see anything
obviously wrong with the code, so is this a bug?
Thanks,
Nathan
