signer information errors in org.eclipse.jdt classes

[joelmoniz]

A sketch with only a setup() method in it does not seem to be displaying properly. The sketch used is:

void setup() {
  size(320, 240);
  rect(20,20,50,50);
}

The sketch throws the following error stack trace repeatedly:

java.lang.SecurityException: class "org.eclipse.jdt.core.compiler.IScanner"'s signer information does not match signer information of other classes in the same package

(etc.)

The present output with the sketch is as follows:

However, the following sketch works fine, but still throws the above mentioned error stack trace continuously, :

void setup() {
  size(320, 240);
}

void draw() {
  rect(20,20,50,50);
}

And its output is as expected:

I think that the AST exception is another issue. The setup issue is likely the same as #3315.

@joelmoniz That looks like you have Eclipse JARs somewhere in your CLASSPATH (or you're using a bad mode) that are conflicting.

The other part is indeed #3315.

[joelmoniz]

Thank you. Indeed, there was something wrong with the JAR files somewhere, and an ant clean followed by a fresh build fixed the java.lang.SecurityException. I've added the rest of the information to #3315 in this comment before closing this issue.
