-------------------------------------
Summary: Lucene 4 bundles are missing META-INF/services files
Key: SMX4-1717
URL: https://issues.apache.org/jira/browse/SMX4-1717
Project: ServiceMix 4
Issue Type: Bug
Components: Bundles
Affects Versions: bundles-2014.01
Reporter: Severin Gehwolf
We are using the servicemix lucene bundles for Thermostat[1]. However, since
lucene 4 the release JARs use Java's ServiceLoader mechanism for loading
codecs. Since the META-INF/services files are missing from the servicemix
lucene bundles any use of IndexWriterConfig will fail with:
Exception in thread "pool-1-thread-1" java.lang.ExceptionInInitializerError
at
org.apache.lucene.index.LiveIndexWriterConfig.<init>(LiveIndexWriterConfig.java:122)
at
org.apache.lucene.index.IndexWriterConfig.<init>(IndexWriterConfig.java:165)
Caused by: java.lang.IllegalArgumentException: A SPI class of type
org.apache.lucene.codecs.Codec with name 'Lucene46' does not exist. You need to
add the corresponding JAR file supporting this SPI to your classpath.The
current classpath supports the following names: []
at org.apache.lucene.util.NamedSPILoader.lookup(NamedSPILoader.java:109)
at org.apache.lucene.codecs.Codec.forName(Codec.java:95)
at org.apache.lucene.codecs.Codec.<clinit>(Codec.java:122)
The fix is to convince the maven-shade plugin to include META-INF/services
directory in the dep-reduced bundle jar. See:
