Hi, when running the JOSM-latest build downloaded from the website [1], there is plenty of log output from JCS, such as: [INFO] BlockDiskCache - Region [TMS_BLOCK_v2] Cache file root But with a local ant build, it doesn't show at all. Any idea why this is the case? [1] https://josm.openstreetmap.de/download/josm-snapshot-12015.jar Paul
