I have the same jar files across both methods of invocation so it's not the classpath. But your question about the getResourceAsStream() line got me thinking. I researched it a bit, and found that the behavior of this method will vary depending on what ClassLoader is active in the current context. Which ClassLoader you get is in turn affected by any number of things, including third party libraries and eclipse plugins. If I restrict my command line classpath specification explicitly to the minimal set of UIMA and OpenNLP jars that I need, it runs fine. I had been using wildcard syntax. I'm not sure how unreferenced libs could affect the ClassLoader, however. So, not the most satisfying resolution, but a resolution nonetheless. Given the nature of the issue, I would have expected the eclipse context to exhibit the problem, not the command line, though perhaps eclipse takes extra care in ClassLoader management. Thanks, Jörn.
