Problem while using java sdk api retrieveObjectProperties error

[chelsykim]

It is a problem that occurs while using javasdkapi, but it does not happen unconditionally.

It seems to occur intermittently.

It seems to occur when multiple processes are collected in one vcenter at the same time, or when the number of hosts or vm is large.

I wonder why this problem occurs.

The Exception log is as follows.
17:58:30.770 ERROR com.vmware.vim25.mo.ManagedObject.retrieveObjectProperties(ManagedObject.java:149)
17:58:30.771 ERROR com.vmware.vim25.mo.ManagedObject.getCurrentProperty(ManagedObject.java:170)

Thank you for your reply.
My current condition seems to occur in special circumstances, usually without any problems. For example, if the same program requests many different api from the same vcenter at the same time, it may seem like that.
