Memory leak - version 3.9.0 #695

I encountered a problem, I used version 2.70.0 and found "com.gargoylesoftware.htmlunit.javascript.HtmlUnitContextFactory$TimeoutContext

net.sourceforge.htmlunit.corejs.javascript.Interpreter$CallFrame

net.sourceforge.htmlunit.corejs.javascript.ConsString” takes up almost 5G of memory. when I set webClient.getOptions().setJavaScriptEnabled(false), I don't hava this problem. I also tried the latest version 3.9.0 , but it doesn't work.
