This error can arise from using Java 9.x rather than 8.x with Stanford CoreNLP. Per the developers (https://stanfordnlp.github.io/CoreNLP/download.html), adding --add-modules java.se.ee to the startup command fixes things. In the camr codebase, the command is specified in stanfordnlp/corenlp.py line 443 (where it looks like you've already upped the memory option to 2500m). So:
start_depparser = "%s -Xmx1800m -cp %s %s %s %s %s"
can be changed to:
start_depparser = "%s -Xmx1800m -cp %s --add-modules java.se.ee %s %s %s %s"

I have encountered the same problem as you, how do you solve it?

[ieremiasviorel]

I have switched from open-jdk 11 to oracle-jdk 8 on ubuntu 18 and it works.

[goodmami]

I've found that open-jdk 8 works, too. No need for the Oracle distribution. Just make sure you've purged your system of any newer JDK libraries if they were previously installed.

[zy-zhangying]

I tried it. I can achieve English AMR analysis,I can not achieve Chinese AMR analysis
