----------------------------------
Summary: Jamm exceptions "JVM prevents jamm from accessing
subgraph - cache sizes may be underestimated"
Key: BEAM-14167
URL: https://issues.apache.org/jira/browse/BEAM-14167
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Sam Whittle
Assignee: Luke Cwik
Can we fix these somehow? At a minimum we should catch them when weighing and
not cache the state.
