RFR: 8263206: assert(*error_msg != '\0') failed: Must have error_message while parsing -XX:CompileCommand=unknown

[Jie Fu]

Hi all,

The following assert fired while parsing '-XX:CompileCommand=unknown' .

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/home/jvm/jdk/src/hotspot/share/compiler/compilerOracle.cpp:688), pid=76463, tid=76464
#  assert(*error_msg != '\0') failed: Must have error_message
#
# JRE version:  (17.0) (fastdebug build )
# Java VM: OpenJDK 64-Bit Server VM (fastdebug 17-internal+0-adhoc.jvm.jdk, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# V  [libjvm.so+0x9b1f5c]  CompilerOracle::print_parse_error(char*, char*)+0xdc
#

It would be better to fix it.

Testing:
  - tier1~3 on Linux/x64

Thanks.
Best regards,
Jie
