Instrumentation fails on Java 14

[JCWasmx86]

Steps to reproduce:

git clone https://github.com/i-net-software/JWebAssembly.git
cd JWebAssembly
gradle clean&&gradle test

Output: ...Omitted... (Everything normal)

Task :test java14instrumentation.txt

I tried commenting out in build.gradle:

apply plugin: 'jacoco'
jacocoTestReport {
    tasks.coveralls.dependsOn it
    reports {
        xml.enabled = true  // coveralls plugin depends on xml format report
        html.enabled = true
    }
}
check.dependsOn tasks.coveralls

Now the tests are running and some are failing: FailingTests.txt testReports.zip

Next I installed java 11: openjdk 11.0.7-ea 2020-04-14 OpenJDK Runtime Environment (build 11.0.7-ea+9-post-Debian-1) OpenJDK 64-Bit Server VM (build 11.0.7-ea+9-post-Debian-1, mixed mode, sharing)

Instrumentation failed and those tests, too.

Java 14 Version: openjdk 14.0.1 2020-04-14 OpenJDK Runtime Environment (build 14.0.1+7-Debian-1) OpenJDK 64-Bit Server VM (build 14.0.1+7-Debian-1, mixed mode, sharing)

OS: Linux 5.6.0-1-amd64 #1 SMP Debian 5.6.7-1 (2020-04-29) x86_64 GNU/Linux

Java 11 or higher required Lambdas for some of the tests. Lambdas are currently not supported (see main page). Currently only Java 8 works with all JUnit tests.

I hope I can implement Lambdas in 1-2 month.
