ADDITIONAL SYSTEM INFORMATION :
- Windows 10 (20H2, 19042.1165)
- OpenJDK 16.0.2 (Temurin build 16.0.2+7)

A DESCRIPTION OF THE PROBLEM :
Compiling a source file with a SimpleTypeVisitor8 anonymous class used in Stream.filter crashes javac. This seems to also require a following Stream.map call (other stream methods might trigger this too), as well as passing this stream call chain to a method as a parameter.

This also happens with a more complex stream chain with a terminal operation at the end, but I stripped the source code into a minimal example.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Put the source in a file named Broken.java
2) Compile the file with "javac Broken.java"

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The code compiles successfully.
ACTUAL -
The compilation fails with the following error diagnostic:

An exception has occurred in the compiler (16.0.2). 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.

CUSTOMER SUBMITTED WORKAROUND :
Replacing the anonymous class with a named class (a nested one, for example)

FREQUENCY : always
