I’m looking for a compiler to translate Java bytecode to platform-independent C code before runtime (Ahead-of-Time compilation).
I should then be able to use a standard C compiler to compile the C code into an executable for the target platform. I understand this approach is suitable only for certain Java applications that are modified infrequently.
So what Java-to-C compilers are available?
I could suggest a tool called JCGO which is a Java source to C translator. If you need to convert bytecode then you can decompile the class files by some tool (e.g., JadRetro+Jad) and pass the source files to JCGO. The tool translates all the classes of your java program at once and produces C files (one .c and .h for each class), which could, further, be compiled (by third-party tools) into highly-optimized native code for the target platform. Java generics is not supported yet. AWT/Swing and SWT are supported.
