High CPU usage and lots of exceptions in log
已回答
IntelliJ consumes around 30% CPU on my 8 core machine. I thought that was a little excessive so I looked into the log and saw a lot of "java.lang.AssertionError: Stub and PSI element type mismatch in StringsKt.class: stub , AST MODIFIER_LIST; Element(MODIFIER_LIST)". I tried invalidating the cache and restarting. Didn't help. Any ideas?
Configuration:
IntelliJ IDEA 2016.2.4 Build #IC-162.2032.8
JDK: 1.8.0_112-release
VM: OpenJDK 64-Bit Server VM
OS: Linux
