JVM implements the WORA features of Java through bytecode interpretation, platform-independent APIs and dynamic class loading: 1. Bytecode is interpreted as machine code to ensure cross-platform operation; 2. Standard API abstract operating system differences; 3. Classes are loaded dynamically at runtime to ensure consistency.

The latest version of Java effectively solves platform-specific problems through JVM optimization, standard library improvements and third-party library support. 1) JVM optimization, such as Java11's ZGC improves garbage collection performance. 2) Standard library improvements, such as Java9's module system reducing platform-related problems. 3) Third-party libraries provide platform-optimized versions, such as OpenCV.

The JVM's bytecode verification process includes four key steps: 1) Check whether the class file format complies with the specifications, 2) Verify the validity and correctness of the bytecode instructions, 3) Perform data flow analysis to ensure type safety, and 4) Balancing the thoroughness and performance of verification. Through these steps, the JVM ensures that only secure, correct bytecode is executed, thereby protecting the integrity and security of the program.

Java's platform independence is continuously enhanced through technologies such as JVM, JIT compilation, standardization, generics, lambda expressions and ProjectPanama. Since the 1990s, Java has evolved from basic JVM to high-performance modern JVM, ensuring consistency and efficiency of code across different platforms.

How does Java alleviate platform-specific problems? Java implements platform-independent through JVM and standard libraries. 1) Use bytecode and JVM to abstract the operating system differences; 2) The standard library provides cross-platform APIs, such as Paths class processing file paths, and Charset class processing character encoding; 3) Use configuration files and multi-platform testing in actual projects for optimization and debugging.

GraalVM enhances Java's platform independence in three ways: 1. Cross-language interoperability, allowing Java to seamlessly interoperate with other languages; 2. Independent runtime environment, compile Java programs into local executable files through GraalVMNativeImage; 3. Performance optimization, Graal compiler generates efficient machine code to improve the performance and consistency of Java programs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
