Trejkaz created LUCENE-6655:
-------------------------------
Summary: StandardTokenizerFactory constructor fails if the passed
in map is immutable
Key: LUCENE-6655
URL: https://issues.apache.org/jira/browse/LUCENE-6655
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 5.1
Reporter: Trejkaz
One of our tests tried to initialise a StandardTokenizer by passing a version
into the factory. Unfortunately, this required passing a map:
{code}
return new StandardTokenizerFactory(ImmutableMap.of(
AbstractAnalysisFactory.LUCENE_MATCH_VERSION_PARAM,
Version.LUCENE_4_6_1.toString()
)).create();
{code}
This then fails:
{noformat}
java.lang.UnsupportedOperationException
at com.google.common.collect.ImmutableMap.remove(ImmutableMap.java:338)

org.apache.lucene.analysis.util.AbstractAnalysisFactory.get(AbstractAnalysisFactory.java:122)

org.apache.lucene.analysis.util.AbstractAnalysisFactory.<init>(AbstractAnalysisFactory.java:71)

org.apache.lucene.analysis.util.TokenizerFactory.<init>(TokenizerFactory.java:70)
at
org.apache.lucene.analysis.standard.StandardTokenizerFactory.<init>(StandardTokenizerFactory.java:42)
{noformat}
I suspect that someone put in a `remove` when it should have been a `get`...
bit of a weird mistake to make, especially when you don't know whether the map
will permit it.
I haven't verified whether the same occurs in later versions but getting
updated to 5.2.1 will probably be the next thing on my list.
