Expected and Results

When attempting to shade and relocate a class that has string constants of descriptors & signatures for fields & methods, the constants are only partially relocated.

For the examples below, assume a shadowJar task of shadowJar { relocate 'org.package', 'shadow.org.package' }

Here are some examples of string constants that are or are not relocated properly

• Lorg/package/ClassA; is properly relocated to Lshadow/org/package/ClassA;
• Lorg/package/ClassA;Lorg/package/ClassB; fails to relocate ClassB resulting in Lshadow/org/package/ClassA;Lorg/package/ClassB;
• Ljava/lang/Object;Lorg/package/ClassB; fails to relocate ClassB
• (Lorg/package/ClassA;Lorg/package/ClassB;) fails to relocate both ClassA and ClassB
• ()Lorg/package/ClassA;Lorg/package/ClassB; fails to relocate both ClassA and ClassB

I could list a lot of similar examples, but you probably get the point by now.

Related environent and versions

Environment

• Shadow Gradle Plugin 9.0.0-beta12
• Gradle 8.14-rc-1
• JDK GraalVM CE 24
• IDE IntelliJ Community 2025.1
• OS Windows 11

Reproduction steps

1. Add org.mozilla:rhino:1.7.15 as a shaded dependency in gradle
2. Configure the shadowJar task for relocation relocate 'org.mozilla', 'shadow.org.mozilla'
3. Build the jar
4. Open shadow.org.mozilla.javascript.optimizer.BodyCodegen.class from the built jar and notice the many string constants that failed to relocate properly

Anything else?

I tried using an include when relocating in hopes that using regex would be able to catch these cases, but from my understanding the relocate task only matches the start of a string.

I also found that using relocate '()Lorg/mozilla', 'Lshadow/org.mozilla' does catch stuff like ()Lorg/mozilla/javascript/Context;, but it still only works for the first class in the case of multiple org.mozilla classes being present in the signature.

Similarly, I found that trying to use relocate '(Lorg/mozilla', 'Lshadow/org.mozilla' fails to build due to a regex parser failing, but I find it strange that the () in ()Lorg/mozilla is treated as a string literal instead of a capturing group. From what I tested, regex does not seem to work with relocation other than include, exclude, and maybe any other closure parameters.
