ADDITIONAL SYSTEM INFORMATION :
# JRE version: OpenJDK Runtime Environment (8.0_392) (build 1.8.0_392-internal-fastdebug-b00)
# Java VM: OpenJDK 64-Bit Server VM (25.392-b00-fastdebug compiled mode linux-amd64 compressed oops)
A DESCRIPTION OF THE PROBLEM :
I ran a modified regression test case on JDK8u392 and found that the JVM crashed with -Xcomp options.
The modifications I made are in lines 35 to 40 of the code. The error message obtained after execution does not match the bug corresponding to the original regression test, which isJDK-8285835. Additionally, I only used the -Xcomp option, which is different from the options used in the original regression test. I believe this is a new issue that needs to be addressed.
