Protect Java source code beyond obfuscation

Java class files are easily reverse-engineered. The characteristics that allow Java applications to run anywhere make reverse translation direct.

There are many Java decompilers available on the market that can generate surprisingly readable source code. Anyone with general programming skills can download a Java decompiler, run your application through it, and read the source code almost as if they were reading open source code.

Confusion of Existing Issues

Due to the high semanticity of JVM bytecode, it makes it very easy to analyze and read the code, even after obfuscation, with a little patience, the program's execution logic can still be figured out. Even with very good obfuscators, static analysis can be made very difficult, but the running logic can still be easily analyzed using dynamic debugging. Writing dynamic debugging tools is not a very complex task, therefore obfuscation is not a reliable protection solution.
