Scott Wegner updated BEAM-408:
------------------------------
Description:
[FindBugs
DM_NEXTINT_VIA_NEXTDOUBLE|https://github.com/apache/incubator-beam/blob/58a029a06aea1030279e5da8f9fa3114f456c1db/sdks/java/build-tools/src/main/resources/beam/findbugs-filter.xml#L209]:
Use the nextInt method of Random rather than nextDouble to generate a random
integer
Applies to:
[ProxyInvocationHandler.hashCode|https://github.com/apache/incubator-beam/blob/58a029a06aea1030279e5da8f9fa3114f456c1db/sdks/java/core/src/main/java/org/apache/beam/sdk/options/ProxyInvocationHandler.java#L96].
This random value is used as a pseudo-unique value for #hashCode(), although
the default Object.hasCode() implementation does the same thing, so this should
be unnecessary.
This is a good starter bug. When fixing, please remove the corresponding
entries from
[findbugs-filter.xml|https://github.com/apache/incubator-beam/blob/master/sdks/java/build-tools/src/main/resources/beam/findbugs-filter.xml]
and verify the build passes.

Its mutating methods are all marked synchronized otherwise.
