Opentelemetry javaagent crashsed with DCEVM, due to StackOverflow caused by endless loadHelperClass.

Describe the bug

When using with DCEVM, OpenTelemetry javaagent failed to start, with error logs:

FATAL ERROR in native method: processing of -javaagent failed

Steps to reproduce

• As described in https://github.com/dcevm/dcevm/, patch the JDK. I'm using JDK 8.
• Add OpenTelemetry Javaagent to the JVM arguments.

Expected behavior

It should start normally.

Actual behavior

It crashes.

Javaagent or library instrumentation version

v2.12.0

Environment

JDK: 8
OS: CentOS amd64

Additional context

If I use invokedynamic, it will crash with:

Tip

_{React with 👍 to help prioritize this issue. Please use comments to provide useful context, avoiding +1 or me too, to help us triage it. Learn more here.}

Start with io.opentelemetry.javaagent.bootstrap.InjectedClassHelper.loadHelperClass at line 55 and trace the recursive ClassLoader.loadClass loop shown in the stack trace. Compare the startup path through OpenTelemetryAgent.startAgent and the invokedynamic path through IndyBootstrapDispatcher. Done means the agent starts normally on patched JDK 8 with DCEVM and does not produce the reported StackOverflowError or BootstrapMethodError.
