Hello
@YanfangLin1 -
I have also observed these issue working with Java based application in BP version 6.3.2,6,4,1 and in 6.9. in case- highlight was also working slow and BP crashed on reading the table inside the java application.
What you can try at this moment is to follow some of the best practice w.r.t working on this kind of application. below is the course on BP university which talks about that. plus the known issue and its workaround for this issue.
Lets wait to hear from other community member.. If it impacting your automation in a big way- you can raise ticket to BP support to get detailed solution around this.
