Package io.opentelemetry.javaagent.bootstrap

Class Java8BytecodeBridge

java.lang.Object

io.opentelemetry.javaagent.bootstrap.Java8BytecodeBridge

public final class Java8BytecodeBridge
extends Object

A helper for accessing methods that rely on new Java 8 bytecode features such as calling a static interface methods. In instrumentation, we may need to call these methods in code that is inlined into an instrumented class, however many times the instrumented class has been compiled to a previous version of bytecode and so we cannot inline calls to static interface methods, as those were not supported prior to Java 8 and will lead to a class verification error.
