I encountered an error when I used the following code， How can I fix it
ForDeclaredMethods visitor = advice.on(methodMatcher) .readerFlags(ClassReader.SKIP_FRAMES) .writerFlags(ClassWriter.COMPUTE_FRAMES);
And I couldn't remove COMPUTE_FRAMES because the obfuscation would conflict with Bytebuddy . I want to know what causes it and I didn't use try catch but he still got an error . This error can be reproduced using a code sample with JDBC and appears without obfuscation
Byte Buddy should handle obfuscated code. Are you using the latest version?
Other than that, the exception states what it is: with legacy blocks, frame computation is not supported.
