Description

[ecj-lint] 6. ERROR in /home/gus/projects/apache/lucene-solr/code/lucene-solr/solr/solrj/src/java/org/apache/solr/common/cloud/ZkStateReader.java (at line 177)
[ecj-lint] new ConditionalExpiringCache<>(new Predicate<>() {
[ecj-lint] ^^^^^^^^^
[ecj-lint] '<>' cannot be used with anonymous classes

Writing it as 

new ConditionalExpiringCache<>(new Predicate<Entry<String, VersionedCollectionProps>>() {

will pass precommit, but now that we are in java 11 the simpler syntax should be allowed.
