http://issues.apache.org/bugzilla/show_bug.cgi?id=42696 Summary: OutOfMemoryError using unzip Task Product: Ant Version: 1.7.0 Platform: PC OS/Version: Windows XP Status: NEW Severity: major Priority: P2 Component: Core tasks AssignedTo: dev@ant.apache.org ReportedBy: [EMAIL PROTECTED] If I try to expand a rather huge zip file (in my case 42910 files, 783359kb uncompressed, 66906kb compressed) using the unzip task I get a java.lang.OutOfMemoryError: requested 37904 bytes for Chuck::new. Out of swap space? My Java Options (Jdk 1.5.0_08 / Jdk 1.6_01) are ANT_OPTS=-XX:NewRatio=2 -Xms512m -Xmx1024m -verbose:gc -XX:+PrintGCDetails on a windows xp pro 32-bit system with a total of 2 GB memory available. The problem now seems that this operation does not need much memory from the heap, so only one gc happens [GC [DefNew: 139776K->17472K(157248K), 0.1300398 secs] 139776K->29555K(506816K), 0.1301295 secs] while the memory usage given by the windows task manager for the java process constantly increases towards 1GB before the process terminates. If I reduce either Xms or increase NewRatio more gc happen and the memory usage as shown by the task manager never increases to more than 400 MB. At each gc it drops to 200 MB or less. Decreasing Xms or increasing NewRatio is obviously a valid workaround for me, but nevertheless it is some kind of a memory leak here. I even tried to find a cause for this (native) memory leak and it seems to be within org.apache.tools.zip.ZipFile. For me it seems that "new Inflater(true)" causes this problem (though changing it simply to false will of course not work), because the problem still occurs if you comment out "extractFile" method in Expand.java such that nothing is really done except opening up input streams from the ZipFile for a number of ZipEntry objects. So maybe this is in its core not a bug of ant, but a bug of the native java implementation for windows. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
