---------------------------------------
Resolution: Fixed
Fix Version/s: 2.2
> Unable to set LockFactory implementation via

> Key: LUCENE-812
> URL: https://issues.apache.org/jira/browse/LUCENE-812
> Project: Lucene - Java
> Issue Type: Bug
> Components: Store
> Affects Versions: 2.1
> Reporter: Matthias Kerkhoff
> Assigned To: Michael McCandless
> Fix For: 2.2

> Attachments: LUCENE-812.patch

>
> While trying to move from Lucene 2.0 to Lucene 2.1 I noticed a problem with
> the LockFactory instantiation code.
> During previous tests we successfully specified the LockFactory
> implementation by setting the property
> ${org.apache.lucene.store.FSDirectoryLockFactoryClass} to
> "org.apache.lucene.store.NativeFSLockFactory".
> This does no longer work due to a bug in the FSDirectory class. The problem
> is caused from the fact that this
> class tries to invoke the default constructor of the specified LockFactory
> class. However neither NativeFSLockFactory
> nor SimpleFSLockFactory do have a default constructor.
> FSDirectory, Line 285:
> try {
> lockFactory = (LockFactory) c.newInstance();
> } catch (IllegalAccessException e) {
> throw new IOException("IllegalAccessException when instantiating
> LockClass " + lockClassName);
> } catch (InstantiationException e) {
> throw new IOException("InstantiationException when instantiating
> LockClass " + lockClassName);
> } catch (ClassCastException e) {
> throw new IOException("unable to cast LockClass " + lockClassName
> + " instance to a LockFactory");
> }
> A possible workaround is to not set the property at all and call
> FSDirectory.setLockFactory(...) instead.
