Shai Erera commented on LUCENE-2688: ------------------------------------ I don't understand why does an Android app need to lock the index at all, and even if -- can't SimpleFS work? java.util.management is perfectly legit, and is not an external dependency or anything. Luckily Android includes java.util.concurrent -- what if it didn't? Would we attempt to fix Lucene too (IndexReader wouldn't work, for example). I personally don't mind if we fix it though, to use nanoTime() or wrap with try-catch and fallback to using nanoTime() there. It's just a question of what do we want to say about Android support. > NativeFSLockFactory throws an exception on Android 2.2 platform as > java.lang.management package is not available on android. > ---------------------------------------------------------------------------------------------------------------------------- > > Key: LUCENE-2688 > URL: https://issues.apache.org/jira/browse/LUCENE-2688 > Project: Lucene - Java > Issue Type: Bug > Components: Store > Affects Versions: 3.0, 3.0.1, 3.0.2 > Environment: Android 2.2 Froyo Nexus One > Reporter: Surinder Pal Singh Bindra > Fix For: 2.9.4, 3.0.3, 3.1, 4.0 > > > NativeFSLockFactory throws an exception on Android 2.2 platform as > java.lang.management package is not available on android. > Looks like FSDirectory defaults to NativeFSLockFactory, and this class > refers to java.lang.management package to generate a unique lock. > java.lang.management is not available in Android 2.2 and hence a runtime > exception is raised.
