SafetyPropagationTransfer is slow because of heavy exception throwing

[ash211]

What happened?

Running with gradle-jfr on one of my repos, I found that my compileJava task was throwing tens of thousands of exceptions:

Looking at the causes, I think it's mostly related to gradle-baseline's SafetyPropagationTransfer class

Specifically the getPath call on this line:

gradle-baseline/baseline-error-prone/src/main/java/com/palantir/baseline/errorprone/safety/SafetyPropagationTransfer.java

Line 1025 in 5f0dd88

TreePath fieldDeclPath = Trees.instance(javacEnv).getPath(accessed);

It seems like that call ends up throwing lots of Exceptions farther down in the com.sun.source code, and heavy use of Exceptions can cause slowness: https://shipilev.net/blog/2014/exceptional-performance/

What did you want to happen?

SafetyPropagationTransfer to run in a way where there aren't a lot of Java exceptions generated, so JFR doesn't show the "Thrown Errors" automated analysis result and ultimately gradle-baseline runs faster.
