Marcel Reutegger updated OAK-9879:
----------------------------------
Component/s: core-spi
(was: blob-plugins)
Description:
FileCacheTest in oak-blob-plugins sometimes fails with
{noformat}
java.lang.AssertionError: expected:<2> but was:<1>
at org.junit.Assert.fail(Assert.java:89)
at org.junit.Assert.failNotEquals(Assert.java:835)
at org.junit.Assert.assertEquals(Assert.java:647)
at org.junit.Assert.assertEquals(Assert.java:633)

org.apache.jackrabbit.oak.plugins.blob.FileCacheTest.assertCacheStats(FileCacheTest.java:566)
at
org.apache.jackrabbit.oak.plugins.blob.FileCacheTest.getDifferentConcurrent(FileCacheTest.java:267)
{noformat}
I can reproduce locally when running the test repeatedly.

Summary: CacheLIRS statistics may return incorrect load count (was:
FileCacheTest.getDifferentConcurrent() fails occasionally)
I turned this into a bug for CacheLIRS. The root cause is a concurrent update
of loadSuccessCount without proper synchronization.
