Subj : Sparodic NoClassDefFoundError: org/mozilla/javascript/optimizer/OptRuntime To : netscape.public.mozilla.jseng From : redcoat Date : Thu Jan 20 2005 02:20 pm Hi, I have a script running very nicely on it's own. However, when I run multiple threads, I get the following error sparodically: java.lang.NoClassDefFoundError: org/mozilla/javascript/optimizer/OptRuntime at org.mozilla.javascript.gen.c1._c0(c:\temp\javascripts\testObjects.js) at org.mozilla.javascript.gen.c1.call(c:\temp\javascripts\testObjects.js ) at org.mozilla.javascript.gen.c1.exec(c:\temp\javascripts\testObjects.js ) at com.lexmark.olympus.action.scripting.ScriptThread.run(ScriptThread.ja va:59) at java.lang.Thread.run(Thread.java:536) Does anyone have any ideas what's going on? thanks! David PS I've obviously checked that OptRuntime is in the classpath, and it must be, as scripts run happily much of the time! .
