Liberty couldn't be started after updating the Liberty and IBM Java Runtime to:
IBM Liberty Version 18.0.0.3 - IBM Java Version 8.0.5.26 (1.8.0_191) or 8.0.5.22 (1.8.0_181)
Exceptions similar to the ones below are reported in the console.log or messages.log:
CWWKE0005E: The runtime environment could not be launched.
CWWKE0018E: An exception occurred while launching the runtime environment: java.lang.VerifyError: JVMVRFY041 invokespecial of wrong initializer; class=com/ibm/ws/kernel/launch/internal/ServerCommandListener, method=init(ILjava/io/File;)V, pc=620

This defect is fixed in 10.7 SP3
Workaround:
1. Stop the JVM/application server
2. Open the appropriate /core/config/toggles pbd file (it can toggles-full.pbd, toggles-full-NoRedef.pbd, toggles-typical.pbd or toggles-typical-NoRedef.pbd)
3. Disable the agent trace(s) according to the exception(s) in the log, there is a corresponding agent trace for each exception, from the above examples:
Type 'com/wily/introscope/agent/probe/io/ManagedFileOutputStream' -> FileSystemTracing
Type 'com/wily/introscope/agent/probe/lang/ManagedThread' -> ThreadTracing
Type 'com/wily/introscope/agent/probe/net/ManagedServerSocket' -> ManagedSocketTracing
based on this, you will need to disable the traces as below:
#TurnOn: FileSystemTracing
#TurnOn: ThreadTracing
#TurnOn: ManagedSocketTracing
4. Start the JVM/application server
