[infinispan-dev] Memory consumption of org.infinispan.marshall.core.JBossMarshaller

Hello, In a recent heap dump analysis I found that org.infinispan.marshall.core.JBossMarshaller consumes a lot of memory(about 46 MB) that seems to be unused. This is due to PerThreadInstanceHolder having ExtendedRiverMarshaller objects that contain big IdentityIntMap objects. Some of those IdentityIntMap instances have a size of 2 million entries, but most of them have sizes of a few 100 thousands. When I look into these IdentityIntMap instances, it seems that the entries are all unused. Is that kind of memory consumption expected or does that indicate a possibly wrong configuration? I am using Infinispan 7.2.4.Final on Wildfly 9.0.1.Final.
