Parser
Since PMD 7.0.0 we use the open source apex-parser, together with Summit AST which translates the ANTLR parse tree into an AST.
When PMD added Apex support with version 5.5.0, it utilized the Apex Jorje library to parse Apex source and generate an AST. This library is however a binary-blob provided as part of the Salesforce Extensions for VS Code, and it is closed-source.
