java.lang.IllegalArgumentException:Self-suppression not permitted

[971758118]

Describe the bug
java.lang.IllegalArgumentException: Self-suppression not permitted
at io.opentelemetry.exporter.internal.marshal.Marshaler.b(Marshaler.java:4)
at io.opentelemetry.exporter.internal.okhttp.ProtoRequestBody.writeTo

Steps to reproduce
ProtoRequestBody
public void writeTo(BufferedSink paramBufferedSink) throws IOException {
this.marshaler.writeBinaryTo(paramBufferedSink.outputStream());
}

Marshaler
public final void writeBinaryTo(OutputStream paramOutputStream) throws IOException {
ProtoSerializer protoSerializer = new ProtoSerializer(paramOutputStream);
try {
writeTo(protoSerializer);
return;
} finally {
try {
protoSerializer.close();
} finally {
protoSerializer = null;
}
}
}

ProtoSerializer implements AutoCloseable, so close() will execute
public void close() throws IOException {
this.output.flush();
this.idCache.clear();
}

in Marshaler.writeBinaryTo(), try() and close() throw a same Throwable instance , so Throwable.addSuppressed() will throw new IllegalArgumentException(SELF_SUPPRESSION_MESSAGE, exception);

What version are you using?
1.21.1

closing in favor of open-telemetry/opentelemetry-java#5239, since I think the relevant code/fix would be there

@trask open-telemetry/opentelemetry-java#5239 that is a duplicate question but not resove, so will there be a fix plan?
eg:
ProtoSerializer.java
@OverRide
public void close() throws IOException {
try {
output.flush();
idCache.clear();
} catch (IOException e) {
throw new IOException(e);
}
}
