http://issues.apache.org/bugzilla/show_bug.cgi?id=33061 Summary: OutOfMemoryError with custom Task in sub-build Product: Ant Version: 1.6.2 Platform: All OS/Version: All Status: NEW Severity: major Priority: P2 Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Our situation: We do have a product build from 80+ modules. Each module has its own buildscript, which is called from a master buildscript. The module build scripts define custom tasks, which make use of thirdparty libraries, for example Dom4J. Now, since we introduced those custom tasks, we get OutOfMemoryErrors somewhere in the build process, even if we give it incredible amounts of memory (1 GB, for example). We don't get this error when putting dom4j.jar into the Ant classpath, so this is a workaround for now. It isn't acceptable for the long term though, as we plan to use even more custom tasks which might use other thirdparty libraries and have to maintain several Ant installations, so this would represent too big a maintenance burden. ---- Reproducing the problem: The attached zipfile contains four files to reproduce the problem: - a minimal custom task using Dom4J - a minimal test.xml that is loaded by the custom task using Dom4J - a subbuild.xml which defines the task and calls it - a build.xml which simply calls subbuild.xml a huge amount of times * compile DummyTask.java * update the classpath definition in subbuild.xml to your local environment * run build.xml using Ant 1.6.2, JDK 1.4.2, without having dom4j.jar in the classpath, giving it 2MB of heap (-mx2m). After some time, you get an OutOfMemoryError * try the same with dom4j.jar in the Ant classpath. You don't get the error. ---- Analysis: Adding some debug statements to AntClassLoader and running Ant in JProfiler, it becomes obvious that neither the AntClassLoader, nor the Dom4J classes used for loading and executing the custom task ever get garbage collected. Those classes build up in memory until it comes to the OutOfMemoryError. -- 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]
