Tweak recovery order to avoid using more aggressive passes if they don't improve things.Ġ.150 ( ).

(optional with -constobf) fold decompiled constant expressions ( thanks ColE) CFR won't do this unless asked as it tries to be true to the bytecode!.

Handle basic loop index obfuscation (confusing offset constants).

Don't resugar negative sized arrays ( thanks x4e).

Handle basic integer (eg /0) control flow obfuscation.Handle dynamic descriptor mismatch obfuscation.Propagate bytecode location (in theory, this can be used to improve debugger support!).

Handle unusual static initialiser access.Handle malicious signatures causing stack overflow.Fix bug with inline assignment inside constructor prelude.Improvement for methodhandle LDCs ( thanks graxcode).Various improvements for ECJ specific patterns.

JAVA ONLINE COMPILER FULL

Improve byte data performance ( thanks CoolMineman)Ġ.151 ( ) As usual, see github for the full change list.

Fix possible infinite loop in changeassignment rewriter.

Fix stack overflow when determining original bytecode location (when showing bytecode loc).

Tweak record support for Java 15+ changes.

JAVA ONLINE COMPILER DRIVERS

Fix race when decompiling with multiple drivers in parallel.

Fix Constantlinks relinking ( thanks Marcono1234).

Be more restrictive inlining lvalues in the presence of possible side effects.

Relink external constants where possible.

Optional resugaring of unobfuscated retrolambda.

Fix possible loop in conditional condenser.

Handle overly lengthy static enum initialisers.

More Java 9+ improvements (java's a moving target these days!)Ĭhange history 0.152 ( ) See github for the full change list.

Without trusting localVariableTypeTable, this is hard.

Correct generic inference for locals which don't escape scope.

Generic reverse inference (forward inference works.

It's got a lot of things missing, which I'm messing with, as and when time makes itself available )

Don't forget to pay attention to NaN in bytecode comparisons.

Related, (but more awkward!) duplicate method signatures in a class.

How does Eclipse's compiler differ from Javac?.

How does Kotlin generate switch on string (i.e.

What's interesting about Java 9 for decompilation?.

JAVA ONLINE COMPILER CODE

The 1.6+ finally block, and code size blowup (come back JSR, all is forgiven.).Class constants in java 1.4 are initialised in an.Field initialisation and the ConstantValue attribute.Lambdas on instance methods also see getClass() introduced, in later Java 8s.and a bit about lambda serialisation boilerplate Inner classes have to fake friendship.Autoboxing is expanded for you by the compiler.How is Java 7's switch-on-string compiled?.or StringConcatFactory vs concatenation in java9+.

JAVA ONLINE COMPILER UPDATE

or just go to github to get master - ( release cadence).įeel free to drop me a line if there's anything you think is particularly broken, bear in mind it's a work in progress (but I'd say on a par with others!) - Or if you want to know when an update is out, I've finally started announcing on twitter - ( about syntactic sugar in compilation.Īll of this stuff is documented (links where I find them) these are things I found particularly interesting while messing around with this. (Feb 2021) (I suggest using latest, but if you spot a regression, it means I'm missing a test.To use, simply run the specific version jar, with the class name(s) you want to decompile (either as a path to a class file, or as a fully qualified classname on your classpath).Īlternately, to decompile an entire jar, simply provide the jar path, and if you want to emit files (which you probably do!) add -outputdir /tmp/putithere ( FAQ) - It'll even make a decent go of turning class files from other JVM languages back into java! :ĬFR will decompile modern Java features - up to and including much of Java 9, 12 & 14, but is written entirely in Java 6, so will work anywhere!
