ConverterDictionary Contains() returns Null though key exists in some cases (Doc ID 1995851.1)

Last updated on OCTOBER 20, 2023

Applies to:

Oracle Coherence - Version 3.7.1.8 and later
Information in this document applies to any platform.

Symptoms

A Coherence*Extend application, which is using the Portable Object Format (POF), has implemented a custom com.tangosol.net.WrapperCacheService to allow it to use a custom com.tangosol.net.cache.WrapperNamedCache to allow it to change the format of the results returned by a call to the implementation's getAll(Collection) method to a HashMap rather than a ConverterCollection.

With this custom implementation in place, when the client receives the results and iterates over the keys it sometimes fails to retrieve the matching value, returning null instead.
