After any Java change, the configuration index was rebuilt from scratch on the next Show
Usages, resolving every dependency's Spring metadata (thousands of Spring Boot properties)
to library members again, and Show Usages waited for it: 15-20 seconds in a Spring Boot +
MyBatis project.
- The Java extension (1.8.0) keeps each dependency JAR's metadata entries across rebuilds
until the JAR's timestamp/size or the project's classpath changes.
- Show Usages shows the Java usages as soon as they are found and adds the configuration
ones when the index takes longer.
Closes#1898
