Kirk Lund created GEODE-2117:
--------------------------------
Summary: Pulse fails to handle float type mbean attributes
Key: GEODE-2117
URL: https://issues.apache.org/jira/browse/GEODE-2117
Project: Geode
Issue Type: Bug
Components: pulse
Reporter: Kirk Lund
The following log messages are logged to Pulse log. These attributes correspond
to fields on MemberMXBean.
Pulse reacts to this by using zero as the value for all of these MBeans
attributes.
This seems to have been introduced by these commits in Feb:

GEODE-907: Switch all fields from floats to doubles
- This is because when Jackson serializes a float (to JSON) it does so
through an implicit cast to a double which alters the precision.
Practically, a number like 23.99F ends up being 23.98999999234D which
messes with unit tests and displaying in the UI.
