-------------------------------
Summary: org.apache.flink.table.runtime.generated.CompileUtils
might cause class leaks
Key: FLINK-25969
URL: https://issues.apache.org/jira/browse/FLINK-25969
Project: Flink
Issue Type: Sub-task
Components: Table SQL / Runtime
Affects Versions: 1.15.0
Reporter: Yun Gao
CompileUtils has two static caches, namely COMPILED_CACHE and
COMPILED_EXPRESSION_CACHE. COMPILED_CACHE is check that it might cache the user
ClassLoaders with strong references, thus it might need be improved.
COMPILED_EXPRESSION_CACHE would need a double check.
