Oracle Labs

Oracle Labs has open-sourced their Ideal Graph Visualizer (IGV), a tool that allows developers to analyze compilation graphs and investigate performance issues. Originally part of GraalVM Enterprise Edition and only available through the Oracle Technology Network (OTN), the primary goal in open-sourcing IGV is to "make it easier for third-party compiler and language developers to use and contribute to it." Further details on other goals and non-goals may be found in this GitHub issue.

Spring Framework

The release of Spring Tools 4.17.1 delivers bug fixes and improvements such as: Eclipse STS 4.17.0 uses 96% processor time on Intel i9; the BootLanguageServerBootApp class is continuously taking all available CPU cycles; and the Language Server background job loads OpenRewrite recipes despite the OpenRewrite options unchecked.
