[osmosis-dev] Irregular java.lang.LinkageError

[Igor Podolskiy]

Alexander,

like with all Java applications: it is _always_ the class path :D 
Judging from the stack trace and the classes involved, you have two 
Xerces jars somewhere. I can think at least of two possible constellations:

1. You have an Osmosis plugin which has a dependency on another version 
of Xerces than the one shipped with Osmosis. That way, you have two 
Xerces jars in your $OSMOSIS_HOME/lib/default or something like that. 
Just delete one of them and everything will probably be fine.

2. You have some kind of a system-wide Xerces installation so that you 
end up with two Xerces jars in your classpath. The solution is to ensure 
that you only have one of them, somehow.

Unfortunately, this is very hard to debug this remotely, because it 
depends on the exact configuration of your system... and it's quite hard 
to reproduce. Please check $OSMOSIS_HOME/conf/plexus.conf, the files in 
$OSMOSIS_HOME/lib/default and $HOME/.openstreetmap/osmosis/plugins. If 
you have 2 xerces-* jars somewhere, this is probably the problem. If 
not, please describe your Osmosis class path as exactly as possible and 
maybe we can find some clues as to where to look further.

Hope that helps,
Надеюсь, это как-нибудь поможет, :)
