signer information does not match [message #335669]

I am trying to do some experimental work the StyledText and would like to
access some of the package protected methods.

So I have created a plugin with package org.eclipse.swt.custom which has
my own renderer and ExtendedStyledText.

In the SWT plugin i have edited the eclipse.inf and added the line:
jarprocessor.exclude = true

I am trying to turn off checking of jar signatures for the SWT plugin.

Unfortunately no matter what I do I get always-
"signer information does not match signer information of other classes in
the same package"

Any any one have any ideas?

By the way there seems to be a typo on this page.
http://wiki.eclipse.org/JarProcessor_Options

jarprocesor is spelled correctly jarprocessor. Which kind of begs the
question which property should be set. But I have tried both of them.

thanks a mil.

My guess is you have two different version of some jar so it gets some
classes for a certain package from one jar and others from another. Check
all your jars for duplicate paths at the package level.

Are you getting this at runtime or at build time?

If at runtime, are you using SWT outside of Eclipse (i.e just adding it
to your java classpath). I would not expect this error in an Eclipse
runtime unless you enabled the runtime signing support and your plugin
which accesses SWT protected methods is a fragment of SWT.

yup I was having this problem at runtime.

I reckon the problem what that the classes where coming from two different
places.

alrighty.

thanks.
