Java d2d: Use source-classes-mapping.txt for JSP mapping

[pombredanne]

JSP deployment analysis is not straight forward because of the multiple indirection and transpilation to Java and compilation to bytecode.

We may be able to use source-classes-mapping.txt for JSP mapping. For instance see:

• https://gitlab.fangeek.cn/hupengxing/ofd_convert/-/blob/ba15d545f20320cb30e66c8d7f892b0fb0b839a9/initial/build/tmp/compileJava/source-classes-mapping.txt

See also:

• https://github.com/gradle/gradle/issues/13601
• https://github.com/search?q="source-classes-mapping.txt"&type=code

These may be from gradle or javac? Likely from an older version of gradle?
