Hi,
this seems to be a bug (or feature?) in the most recent Java 9 build 54:
compile-core:
[mkdir] Created dir:
/home/jenkins/workspace/Lucene-Solr-5.x-Linux/lucene/build/analysis/common/classes/java
[javac] Compiling 461 source files to
/home/jenkins/workspace/Lucene-Solr-5.x-Linux/lucene/build/analysis/common/classes/java
[javac]
/home/jenkins/workspace/Lucene-Solr-5.x-Linux/lucene/analysis/common/src/java/org/apache/lucene/analysis/util/CharArrayMap.java:568:
error: incompatible types: CharArrayMap<CAP#1> cannot be converted to
CharArrayMap<V>
[javac] return new CharArrayMap<>(map, false);
[javac] ^
[javac] where V is a type-variable:
[javac] V extends Object declared in method <V>copy(Map<?,? extends V>)
[javac] where CAP#1 is a fresh type-variable:
[javac] CAP#1 extends V from capture of ? extends V
This is the code:
@SuppressWarnings("unchecked")
public static <V> CharArrayMap<V> copy(final Map<?,? extends V> map) {
if(map == EMPTY_MAP)
return emptyMap();
if(map instanceof CharArrayMap) {
CharArrayMap<V> m = (CharArrayMap<V>) map;
// use fast path instead of iterating all values
// this is even on very small sets ~10 times faster than iterating
final char[][] keys = new char[m.keys.length][];
System.arraycopy(m.keys, 0, keys, 0, keys.length);
final V[] values = (V[]) new Object[m.values.length];
System.arraycopy(m.values, 0, values, 0, values.length);
m = new CharArrayMap<>(m);
m.keys = keys;
m.values = values;
return m;
}
return new CharArrayMap<>(map, false);
}
At least this breaks compiling existing code. Rory, should I open a bug report
with an example code?
