-----------------------------------------
Summary: extractSchemaGenObjects mutates caller's properties map
Key: OPENJPA-2955
URL: https://issues.apache.org/jira/browse/OPENJPA-2955
Project: OpenJPA
Issue Type: Sub-task
Components: jpa
Affects Versions: 4.2.0
Reporter: Maxim Solodovnik
Fix For: 4.2.0
Discussion thread:
https://github.com/apache/openjpa/pull/144#discussion_r3683000132
**(medium)** `extractSchemaGenObjects` calls `map.remove(key)` on the
caller-supplied properties map - this mutates user configuration and throws
UnsupportedOperationException for unmodifiable maps (e.g. `Map.of(...)` passed
to `createEntityManagerFactory`). Can the Writer/Reader values be captured
without mutating the input?
