GWT application fails with IllegalArgumentException in org.objectweb.asm.ClassVisitor

We have a larger GWT application that used to be built with GWT v2.8.0. I am trying to upgrade it to GWT v2.9.0.
Compilation and packaging etc. all works fine, but when I try to start it (via maven using the goal gwt:run) I get the below error and stacktrace.
Any idea anyone, what is causing this and if and how one can fix this?
I am using an AdopOpenJDK v8.0.292.10 (hotspot) as runtime.

Firstly I would make sure you have deleted any GWT caching files/directories. Look in C:\Users\mms\AppData\Local\Temp\ for any files/folders starting with gwt.
Another possibility is that you have dependencies in your project that are using an older version of the asm.jar library that is incompatible with the GWT compiler.
In more detail, com.google.gwt:gwt-dev:2.9.0 is built against org.ow2.asm:7.1 . Check that your project does not have a dependency on ASM that is earlier than 7. (Note that this could be a transitive dependency.)

Unable to download dependencies from Remote Repository behind the proxy in SBT

I am creating a POC where I am trying to download the dependencies from my corporate repository (JFrog) where my build file is :-
build.sbt :-
name := "sbt-test4"
version := "0.1"
scalaVersion := "2.12.8"
resolvers ++= Seq {
"Artifactory" at "https://someurl/artifactory/packagename"
}
credentials += Credentials(new File("credentials.properties"))
libraryDependencies += "ccp.mts.aerospike" % "mts-aerospike_2.12" % "0.2"
credentials.properties :-
realm=Artifactory Realm
host=https://<url>/artifactory
user=<user-id>
password=<password>
Now I am running these commands:-
java -Dhttp.proxyHost=162.158.20.9 -Dhttps.proxyHost=162.158.20.9
-Dhttp.proxyPort=8300 -Dhttps.proxyPort=8300 -Dhttp.nonProxyHosts="*.company.net" -Dhttps.nonProxyHosts="*.company.net" -jar C:\Users\xxxx.xxx034\.IntelliJIdea2018.2\config\plugins\Scala\launcher\sbt-launch.jar
>sbt update
this proxy information I have tried to pass using command itself and "sbtconfig.txt" and "sbtopts" files also.
Even These information I have passed through evn variables like :-
JAVA_OPTS=$JAVA_OPTS -Dhttp.proxyHost=162.158.20.9 -Dhttps.proxyHost=162.158.20.9 -Dhttp.proxyPort=8300 -Dhttps.proxyPort=8300 -Dhttp.proxyUser=uid-Dhttp.proxyPassword=password -Dhttps.proxyUser=uid-Dhttps.proxyPassword=password
SBT_OPTS=$SBT_OPTS -Dhttp.proxyHost=162.158.20.9 -Dhttp.proxyPort=8300 -Dhttp.proxyUser=uid-Dhttp.proxyPassword=password -Dhttps.proxyHost=162.158.20.9 -Dhttps.proxyPort=8300 -Dhttps.proxyUser=uid -Dhttps.proxyPassword=password
but still it I am not able to get the dependencies from remote repositories.
I have also referred :-
SBT 0.13.11 cannot download dependencies behind a proxy
And this is the Error log:-

I have separated files with configs for dev, prod and test mode. Tests use own database to miss possibility to hurt production server(I don't use inmemory database)....

Okay. activator just ignores -Dconfig.resource=env_test.conf for test plugin. When I use application.conf for test purposes (which is default config file) than it works. For application running it works:
./activator -Dconfig.resource=env_dev.conf run
But it's IntelijIdea runs test well with defiled -Dconfig.resource=env_test.conf. It's just funny:)

This exception gets thrown whenever an annotation type can't be loaded. As the message says (and Thomas explained in his response), one scenario where this can happen is when you add a new annotation type during a Dev Mode session.
Another possible way to get this error is not having org.hibernate.validator.constraints.ConstraintComposition on your GWT compiler's classpath. Try compiling with mvn -X gwt:compile and take a look at the classpath used with the GWT compiler. Verify that your GWT compilation classpath includes a .jar with org/hibernate/validator/constraints/ConstraintComposition.class in it.

DevMode (and the GWT Compiler BTW) resolves annotations from bytecode, not source code (to my knownledge, this is the only use of bytecode as source in GWT); so annotations you introduce in your source code can't be seen by DevMode until you restart it.
This is unless the generator that makes use of the annotations uses some tricks to actually load the recompiled bytecode. FYI, GIN used to suffer from this limitation, and starting with 2.0 it uses ClassLoader tricks to mitigate it.
Errai seems to have some tricks to detect you have changed the source code in ways that won't be seen by DevMode (in this case, I suppose by the Bean Validation generator built into GWT, so it cannot be changed to use similar tricskas GIN) and generates an error.
