## Purpose of this pull request
I will run about 15 batch synchronization tasks per minute. When I add
MaxMetaspaceSize = 2g in jvm_options, OOM will appear after about 1.5 hours of
running.
I used Arthas to check and analyze dump image files. I found that the class
loader is created again every time a batch task is submitted. After the batch
task is completed, the class loader is not uninstalled, resulting in the rapid
expansion of the metaSpace area and finally oom. So I added a cache to the
classloader.
