[ jEdit-users ] How does JEdit handle multiple versions of same jar?

[Patrick W. <jed...@pd...>]

JEdit 4.2pre12, Java 1.4.2_03

I'm using CheckStyle 3.4 (the whole release, not the plugin) in a JEdit
plugin I am building. When I run code through the CheckStyle Checker
class, get an Error

java.lang.NoSuchFieldError: tokenTypeToASTClassMap


Discussion groups list this problem as related to using an old version of
the Antlr toolkit, which CheckStyle relies on.

I have integrated the CheckStyle by copying the checkstyle-all-3.4.jar to
the JEdit settings directory. That jar includes antlr.jar. My thought is
that perhaps another plugin has already loaded a separate version of
antlr.jar which is conflicting.

Question: what does JEdit do in this case? Is is possible that a separate
set of antlr classes are being loaded by JEdit? Is this dependent on the
order in which jars are loaded?

I did do a search for "antlr." in my settings/jars directory (where I hav=
e
plugin source code) and found no references. It could be something else.

Thanks
