What steps will reproduce the problem?
1. Installed m2eclipse

moving to JDT core for comment

One of the reasons could be that invalid archive file was added to the project's build path. Can you please check if there are any warnings/errors of an invalid classpath entry?

Comment 3 Michael Matczynski

This error was the result of XML and TXT files on the build path.

What happened is that I wanted to add all the jars in the axis2/lib directory, and simply selected all the files in the directory (which had XML and TXT files mixed in with JAR files).

Seems like the fix is one or both of the following:
1. Java Build Path's "Add JARs..." dialog should filter out all non-JAR files
2. Someone in the callstack should catch the IOException and log/ignore the error.  It doesn't make sense to start throwing exceptions in the error log and preventing content assist from working if this is a recoverable error.

Thanks!
Mike

This should be done in the UI.
Moving to JDT/UI
