I've run into one problem while testing Tika 1.8 with Bixo
It involves a dependency issue involving (of course) Guava, since that project
loves to break their API :(
The bixo-core jar has these transitive dependencies on various versions of
Guava:
Hadoop - 11.0.2
Cascading - 14.0.1
Tika-parsers - 10.0.1
cdm - 17.0
Everyone winds up using version 10.0.1 (note that Tika has a dependency on cdm,
which wants to use 17.0)
The problem is that Hadoop (for any recent version) uses an API from Guava's
cache implementation that no longer exists:
com.google.common.cache.CacheBuilder.build(Lcom/google/common/cache/CacheLoader;)Lcom/google/common/cache/LoadingCache;
java.lang.NoSuchMethodError:
com.google.common.cache.CacheBuilder.build(Lcom/google/common/cache/CacheLoader;)Lcom/google/common/cache/LoadingCache;
at
org.apache.hadoop.io.compress.CodecPool.createCache(CodecPool.java:62)
at org.apache.hadoop.io.compress.CodecPool.<clinit>(CodecPool.java:74)
at
org.apache.hadoop.io.SequenceFile$Writer.close(SequenceFile.java:1272)
at
org.apache.hadoop.mapred.SequenceFileOutputFormat$1.close(SequenceFileOutputFormat.java:79)
So what this means is that anyone trying to use Tika with Hadoop will need to
play games with the class loader to get the older version of Guava - though
that can cause other issues if Hadoop (or Cascading, etc) rely on anything
that's only in the newer Guava API.
Guava 1.0.01 was released about 3.5 years ago; 11.0.2 was from about 3 years
ago. So it seems like we should upgrade to at least 11.0.2
But I don't know if this is enough of an issue to require another RC.

PS - I've created https://issues.apache.org/jira/browse/TIKA-1606 to track this.
