it is indeed when i'm running ant scripts... so one hypothesis is that eclipse's ant runner doesn't close the classloaders used for running ant and the classpath files are just kept open. there doesn't seem to be a configuration option in eclipse to run ant in a separate process or something like that. i see in external tools configurations that all the ant tasks are already specified with 'Separate JVM' (and not 'run in the same JVM as the workspace) damn.
