Petr, please look at it. Very strange. Did it happen again? Do you have your userdir with umnodified layer.bin? Now I probably got it. It have to be a race condition on the lastModified variable. Two threads calling lastModified at once, both finding the lastModified variable negative (index into array). First of them resolves the real value and stores it, then the second finds the real value and treats it like the index. It should be very unlikely to happen, so I won't fix it for 4.0. Fixed. core/src/org/netbeans/core/projects/cache/BinaryFS.java,v1.15 |
