{noformat} SizeableBytes2ObjectOpenCustomHashMapWithCursorQuickCheckTest > scanWithNoModificationsDoesNotReturnDuplicates FAILED java.lang.AssertionError: Property named 'scanWithNoModificationsDoesNotReturnDuplicates' failed ( Expected size: 2 but was: 4 in: [176, 55, 176, 55]): With arguments: [[176, 55]] Original failure message: Expected size: 2 but was: 4 in: [55, 202, 55, 202] First arguments found to also provoke a failure: [[55, 202]] Seeds for reproduction: [5487908098719980972] at org.apache.geode.redis.internal.data.collections.SizeableBytes2ObjectOpenCustomHashMapWithCursorQuickCheckTest.scanWithNoModificationsDoesNotReturnDuplicates(SizeableBytes2ObjectOpenCustomHashMapWithCursorQuickCheckTest.java:85) Caused by: java.lang.AssertionError: Expected size: 2 but was: 4 in: [55, 202, 55, 202] at org.apache.geode.redis.internal.data.collections.SizeableBytes2ObjectOpenCustomHashMapWithCursorQuickCheckTest.scanWithNoModificationsDoesNotReturnDuplicates(SizeableBytes2ObjectOpenCustomHashMapWithCursorQuickCheckTest.java:85){noformat} This failure is due to the test assuming that more than one scan is necessary to scan the entire set, but for small set sizes (the set in the failure above only has 2 members) it's possible that the first scan will return all elements and a cursor value of 0, meaning that the second scan will also return all elements, leading to duplicate elements in the result. -- This message was sent by Atlassian Jira (v8.20.1#820001)
