Shaunak Das updated TINKERPOP-1045:
-----------------------------------
Description:
I try to use a HashMap that has keys of type Integer, and send the following
request:
gremlin> map = [1: "hello", 2: 3]
==>1=hello
==>2=3
gremlin> map[1]
==>hello
gremlin> map[2]
==>3
gremlin> client = Cluster.build().create().connect().alias("graph.g")
==>org.apache.tinkerpop.gremlin.driver.Client$ReboundClusteredClient@cda4919
gremlin> client.submit('1+1').all().get()
==>result{object=2 class=java.lang.Integer}
gremlin> client.submit('map[1]', map).all().get()
The client-side ends up hanging. The Gremlin Server logs give this, which is to
be expected, as explained to me by Stephen:
WARN [gremlin-server-worker-1] 2015-12-16 00:34:26,609 Slf4JLogger.java:151 -
An exceptionCaught() event was fired, and it reached at the tail of the
pipeline. It usually means the last handler in the pipeline did not handle the
exception.
