| The main uses of the Ant integration module are self-contained and do |

| <!-- |
| <question id="compat-standards" when="init"> |
| Does the module implement or define any standards? Is the |
| implementation exact or does it deviate somehow? |
| </question> |
| --> |
| <answer id="compat-standards"> |
| <p> |
| Insofar as Ant can be considered a standard, it implements the |
| standard behavior of running an Ant script. The implementation should |
| behave quite similarly to what the normal Ant command-line usage does |
| (since it delegates to the Ant library internally and only replaces |
| the command-line wrapper with an IDE wrapper). Since the Ant project |
| does not publish a formal specification of how Ant should behave, |
| there is no objective criterion for judging the fidelity. |
| </p> |
| <p> |
| Likely areas of difference between command-line and IDE usage: |
| obscure class loader scenarios (since the IDE must load Ant in a |
| special class loader, whereas the command-line tool may do it |
| differently); system properties set in the IDE but not on the command |
| line; etc. Generally, well-written scripts and tasks are not affected |
| by these differences, but occasionally problems arise (they are |
| treated as bugs). |

| |
| <hint> |
| Very helpful for reading settings is to store version number |
| there, so future versions can decide whether how to read/convert |
| the settings and older versions can ignore the new ones. |

| --> |
| <answer id="exec-classloader"> |
| <p> |
| Yes, several class loaders are created: |
| </p> |
| <ol> |
| <li> |
| <p> |
| Ant itself is loaded from a class loader containing just |
| <code>ant/lib/*.jar</code> (or generally from |
| <code>lib/*.jar</code> in a user-specified Ant installation |
| directory), plus any user-specified additional classpath |
| entries and entries from <code>AutomaticExtraClasspathProvider</code>. |
| </p> |
| <p> |
| <code>InstalledFileLocator</code> is used to find |
| <code>ant/lib/ant.jar</code> and the default Ant installation |
| is taken to be the parent directory of the containing directory |
| of this (e.g. <code>ide/ant/</code>). |
| </p> |
| <p> |
| If any files <code>ant/patches/*.jar</code> exist, they are |
| loaded at the front of the classpath, to permit an IDE distribution |
| to bundle a version of Ant with patches (e.g. for #47708). |
| </p> |
| </li> |
| <li> |
| <p> |
| <code>ant/nblib/bridge.jar</code> is loaded from a class |
| loader delegating to both the main Ant loader, and the Ant |
| module's class loader. |
| </p> |
| </li> |
| <li> |
| <p> |
| Each module with a custom definition JAR in |
| <code>ant/nblib/*.jar</code> gets a class loader delegating |
| to both the main Ant loader, and that module's class loader. |

| <code>IntrospectedInfo</code> should be thread-safe and fires changes |

| <answer id="perf-mem"> |
| <p> |
| The main question is how much memory a build consumes as it runs. Can |
| be substantial - will easily keep a default 96Mb heap filled - but |
| does not appear to leak. Ant itself mostly uses memory linearly (i.e. |
| allocates and soon releases it), except for deeply nested build |

| <answer id="perf-scale"> |
| <p> |
| Most interesting criteria relate to performance of Ant itself, which |
| seems fine. |

| <p> |
| Adding an extra module with custom task definitions add a small |
| overhead (10msec?) to launching an Ant script. The time is largely |
| spent in Ant itself so is difficult to optimize out. |

| NetBeans provide a logical wrapper over plain files called |
