| If you have problems with the tasks not solved by the documentation, | |

| directly on the command line. | |

| If the problem occurs on the command line also, then the problem | |
| is not in the task. | |

| </p></li><li><p><a name="d0e2659"></a> | |
| If the problem does not occur on the command line, then it may | |

| handling of them. | |
| </p></li><li><p><a name="d0e2662"></a> | |
| If the build script looks correct and the problem only occurs when | |

| </p><p> | |
| When running Ant build scripts under Eclipse 2.x variants, you will get a | |
| VerifyError because the Eclipse Ant support fails to isolate the Ant runtime | |
| properly. To run in this context, set up iajc to fork (and use forkclasspath). | |
| Eclipse 3.0 will fork Ant processes to avoid problems like this. | |
| </p><p> | |
| Memory and forking: Users email most often about the ajc task running | |
| out of memory. | |
| This is not a problem with the task; some compiles take a lot of | |
| memory, often more than similar compiles using javac. | |
| </p><p> | |
| Forking is now supported in both the | |
| <a href="antTasks-adapter.html">Ajc11CompilerAdapter (javac)</a> and | |
| <a href="antTasks-iajc.html">AjcTask (iajc)</a>, | |
| and you can set the maximum memory available. | |
| You can also not fork and increase the memory available to Ant | |
| (see the Ant documentation, searching for ANT_OPTS, | |
| the variable they use in their scripts to pass VM options, | |
| e.g., ANT_OPTS=-Xmx128m). | |
