Description
we've seen some java11 jenkins builds that have failed due to an AssertionError being thrown by HashMap.put as used in LRUCache – in at least one case these failures are semi-reproducible. (the occasional "success" is likely due to some unpredictibility in thread contention)
Some cursory investigation suggests that JDK-8205399, first identified in java10, and fixed in java12-b26...
https://bugs.openjdk.java.net/browse/JDK-8205399
There does not appear to be anything we can do to mitigate this problem in Solr.
It's also not clear to me based on th comments in JDK-8205399 if the underlying problem can cause problems for end users running w/assertions disabled, or if it just results in sub-optimal performance
