Unfragile

The request names CFR (the Java class file decompiler), which none of the candidate sources describe; the candidates are general tools, so none directly decompiles Java bytecode per their pages. Named product not shown in sources; the closest related items are below.

A question back: Do you mean CFR, the Java bytecode decompiler, or a different tool? None of the listed sources show a decompiler, so I can't confirm a match for cfr-decompiler.
