Three empty validation messages appear in the eclipse Markers-tab. There is no message, location, description or folder indication in either one.

How to reproduce:
Add the dependency to a war module in eclipse using the m2e plugin:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.4</version>
</dependency>
(adding the dependency to a jar does not result in a validation message)

Execute 'Validate' or import the module as an existing maven project.
Changing the version back to 1.6.3 reduces the number of validation messages to one (1).

I am using:

• Windows 7 (32-bit)
• Eclipse Indigo (SR-1)
• M2E plugin version 1.0.100.20110804-1717 (no newer version exists at this time)
