guava

Usage

For the most part, you should be able to just find+replace all references to com.google.common with dev.mccue.guava.

Consult the original documentation for in-depth usage guides.

What

This module is a soft-fork of Guava which

• Is shaded under dev.mccue.guava
• Has a proper module-info.java
• Has all usages of sun.misc.*, The Security Manager, and finalize() removed.

The work of shading is done by this project. Releases of this and dependent modules should contain the guava release or commit hash from which they are generated.

This is an aggregator module and each package of guava has been split into submodules which can be found here

• dev.mccue.guava.base
• dev.mccue.guava.primitives
• dev.mccue.guava.escape
• dev.mccue.guava.math
• dev.mccue.guava.collect
• dev.mccue.guava.xml
• dev.mccue.guava.html
• dev.mccue.guava.graph
• dev.mccue.guava.hash
• dev.mccue.guava.io
• dev.mccue.guava.net
• dev.mccue.guava.reflect
• dev.mccue.guava.concurrent

Why

• It doesn't seem like guava will be modularized any time soon
• I want to enable more libraries to be fully modular so that the jlink workflow is more viable
• This was fun to do, and it seems as if some people are interested in the results.

Support

I'll try to keep up to date, but if you

• Notice something wrong
• Want me to make a release for a new version
• Want a minute of my time

Feel free to reach out.

Changes made from Guava

• Everything is shaded under dev.mccue.guava
  • com.google.common.util.concurrent is turned into dev.mccue.guava.concurrent, dropping the util
• All usages of sun.misc.Unsafe are removed
  • The unsafe implementation is removed, leaving a safe fallback in LittleEndianByteArray, AbstractFuture, and UnsignedBytes
  • The unsafe implementation in is replaced with a new one based on VarHandles in Striped64
• All usages of sun.misc.JavaLangAccess are removed
  • Replaced with Throwable.getStackTrace in Throwables
• All usages of finalize() are removed
  • FileBackedOutputStream has a constructor which takes a boolean to indicate that resources should be freed on finalization. This was made private and the logic was removed.
• All usages of the Security Manager are removed
  • Types catches an AccessControlException and that could safely be replaced with catching an Exception
  • Explicit uses of the security manager in LittleEndianByteArray, AbstractFuture, UnsignedBytes, and Striped64 were removed along with the code to load sun.misc.Unsafe.
• All usages of java.util.logging.Logger were replaced with java.lang.System.Logger
  • With this change, the only JDK module depended on is java.base.
• All usages of javax.annotation.* classes from com.google.code.findbugs/jsr305 are replaced with equivalent classes from dev.mccue/jsr305
• FinalizableReferenceQueue and associated classes were removed
  • They were rarely used, probably do a job better done by a Cleaner, and I wasn't able to validate that they would behave correctly in a module
• Annotation modules are used via requires static and are not carried over to dependents.
• All annotation usages from com.google.common.annotations and com.google.j2objc.annotations have been removed
• Split into multiple submodules, each with their own module-info.java
• Drops explicit support for GWT, j2objc, j2cl, etc.
• Drops explicit support for android (equivalent to the -jre build)
• Does not include
  • com.google.common.eventbus (Guava docs explicitly recommends against its use)
  • com.google.common.cache (Caffiene covers that use.)
  • com.google.common.annotations (Only @Beta and @VisibleForTesting would be relevant without GWT+etc. testing, and you can make your own pretty easily.)
• Compiled for Java 9+, not Java 8
