A DESCRIPTION OF THE PROBLEM :
Was able to trigger a NullPointerException in javac:

[INFO] Compiling 1 source file to /Users/apiburn/Source/jdk-error/target/test-classes
An exception has occurred in the compiler (17.0.1). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
java.lang.NullPointerException: Cannot invoke "com.sun.tools.javac.code.Type.getThrownTypes()" because "tree.meth.type" is null

REGRESSION : Last worked in version 8u311

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See example maven project: https://github.com/mtday/jdk-error

The code in question uses Jakarta.ws.rs.core classes (Response and GenericType):

Assertions.assertEquals(lists, response.readEntity(new GenericType<>() {}));

This usage of the GenericType class without specifying the parameterized type causes the NPE in javac.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected the compiler to indicate an error in the source code, or to successfully determine the type at compile time and successfully compile the code.
ACTUAL -
NullPointerException thrown by the javac compiler. Full stack trace shown in the example project: https://github.com/mtday/jdk-error

---------- BEGIN SOURCE ----------
https://github.com/mtday/jdk-error
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Two workarounds:

Instead of this line that causes the error:

Assertions.assertEquals(lists, response.readEntity(new GenericType<>() {}));

Use this line:

Assertions.assertEquals(lists, response.readEntity(new GenericType<List<TodoList>>() {}));

Or these two lines:

List<TodoList> results = response.readEntity(new GenericType<>() {});
Assertions.assertEquals(lists, results);

FREQUENCY : always
