Failig to mock Interfaces with Java 14

[blaszczyk]

When using Mockery with ByteBuddyClassImportiser (version 2.12.0) to mock any interface with java 14, it fails with an error like:

java.lang.IllegalStateException: No code generation strategy available
	at org.jmock.imposters.ByteBuddyClassImposteriser.proxyClass(ByteBuddyClassImposteriser.java:167)
	at org.jmock.imposters.ByteBuddyClassImposteriser.access$000(ByteBuddyClassImposteriser.java:41)

	at org.jmock.Mockery.mock(Mockery.java:167)
	at org.jmock.Mockery.mock(Mockery.java:143)

With java 13 and below mocking classes and interfaces worked well using ByteBuddyClassImportiser. Also Mockery with default Importiser can still mock interfaces in java 14.

Thanks, yes for interfaces it would be easier if I used the old mockery strategy

Actually, updating byte buddy manually to the current version (1.10.16) resolved the issue.

[osparking]

I added latest bytebuddy dependency into pom.xml and the problem is gone.
(from the default 1.9.? to

		<dependency>
			<groupId>net.bytebuddy</groupId>
			<artifactId>byte-buddy</artifactId>
			<version>1.14.10</version>
		</dependency>

)
