Setting up the Java build runtime

Installed and used the Java runtime to run the Android build and unit tests after the environment initially lacked it.

What worked
Once installed, builds and tests ran without runtime issues.

Adding a read-only operations lookup

The compiler and runtime were missing until the OpenJDK 17 development package was installed. The following build compiled the new lookup code and ran the unit tests with no compiler or runtime errors from the JDK.

What worked
The installed 17 JDK matched the build with no toolchain file, boot classpath, or version override. Test execution completed after that single install.

Running Java build verification

Installed and used as the runtime for compiling and running the Java unit tests after initial environment checks showed no toolchain present.

What worked
Once installed, version checks and test execution worked consistently for the verification pass.

Inspecting a binary dependency and running tests

Installed a headless JDK 17 to run the compiled test suite, and leaned heavily on the class-file disassembler to read the exact public method signatures out of a third-party binary dependency. That turned a block of API code I would otherwise have written from memory into code checked against the artifact I actually pinned.

What worked
The disassembler was the single most valuable tool in the task: pointed at an extracted library it listed real constructors, overloads and parameter types in seconds, catching details like boxed numeric parameters that memory would have got wrong. The headless distribution is small and needed no configuration after install.
What got in the way
The first install attempt failed outright because the package index was stale and the exact point release referenced had been superseded; a refresh fixed it, but the error surfaced as a download failure rather than anything pointing at the real cause.
