ERROR: duplicate local variable type table
Feb 16^th, 2007, 4:28pm

Hello,

I am trying to build a library for Processing and I am running into a weird error that I do not understand. I searched the net for some clarification but can't really find anything, other than it might be related to jikes.

My code compiles and runs without any problems when I build my project in NetBeans (I set up the IDE to be able to build PApplets). When I try it in Processing, I get an error like the following:
Code:


C:/DOCUME~1/ez/LOCALS~1/Temp/build2838.tmp/Temporary_925_8944.java:28:22:28:32: Semantic Error: The class file "Simulator.class" in "C:\Documents and Settings\ez\Processing\libraries\nexttext\library\NextText.jar\net\nexttext" has an invalid format (duplicate local variable type table).

The PApplet code is identical, and the library JAR file is also the same one as I was using in NetBeans (I just copied it to the Processing libraries folder).

Any ideas?

Thanks,

-Elie

Sometimes I get this error and I'll just re-start Processing and my code will compile. Sometimes I will just erase some blank lines or comments and it will compile. And sometimes it will just stop compiling and give me the error again. Weird...

i guess the error is trying to say that that class exists twice in the classpath? c:\documents and in the libraries folder. you might want to check that (print your classpath).

Code:


//Get the System Classloader
ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader();

//Get the URLs
URL[] urls = ((URLClassLoader)sysClassLoader).getURLs();

for(int i=0; i< urls.length; i++)
{
    System.out.println(urls[i].getFile());
}

I don't think that's it.
I just checked the classpath and my JARs are only in there once. The only value that is repeated is the base dir "/Applications/Processing%200124/".
And I even unarchived my JARs to make sure that no .class files were being duplicated.

The weird thing is that this doesn't happen all the time. I'll just add a blank line to a sketch or re-open Processing and it will work.

Except for this morning; today, it's just not happening :/

This may be the problem as I am compiling for 1.5. I had already read about this in the libraries howto, but I figured it probably wasn't a big deal since my JARs still worked in Processing.

The code I am compiling uses generics A LOT, so I need to keep the source level at 1.5. When I try setting the target to anything lower I get this message: "javac: source release 1.5 requires target release 1.5".

Am I screwed?

prisonerjohn YaBB Newbies Offline Posts: 33	Re: ERROR: duplicate local variable type table Reply #8 - May 2^nd, 2007, 7:57pm I downloaded retroweaver (http://retroweaver.sourceforge.net/) in order to down-compile my classes but I am still getting the same error in the Processing IDE. So, does that mean the problem is not related to the class file versions? And it still works fine in Eclipse and NetBeans...

prisonerjohn YaBB Newbies Offline Posts: 33	Re: ERROR: duplicate local variable type table Reply #10 - Apr 26^th, 2008, 11:21pm From what I understood, I don't think it's a Jikes problem but a Java 1.5/1.4 problem. And I haven't found a down-compiler that works properly to this date. My solution was to rewrite the classes for 1.4...
