Can't step over breakpoint on lambda expression/step filters ignored

If you set a breakpoint on a line of code containing a lambda expression, attempts to step over the code will result in a step into the code. If the lambda expression is a function of the standard library and your step filters are enabled, you will still have to trudge through many .class files.

Environment

• Operating System: Windows 10
• JDK version: 1.8.0_181
• Visual Studio Code version: 1.37.0-insider (system setup)
• Java extension version: 0.7.1 (assuming this refers to the Java Extension Pack)
• Java Debugger extension version: 0.20.0

Steps To Reproduce

1. Extract this to a folder and open that folder in vscode.

2. Set breakpoints on lines 4 and 10 of test.java

3. Debug test.java with the provided launch.json

4. Repeatedly step-in until you have reached line 10. Observe that the debugger has not forced you to view the HashMap.class file or any of the standard libraries.

5. Attempt to step-over line 10. Observe that the debugger has stepped-in.

6. Attempt to step-over again. Observe that you are now viewing the HashMap.class file, despite the settings in launch.json, which should have prevented this.

Current Result

Stepping over a lambda expression with a breakpoint will step in, even if your step filters should prevent this.

Expected Result

Stepping over a lambda expression with a breakpoint should step over the expression. Regardless, step filters should prevent viewing of standard libraries.

Additional Informations

I already tried this on the current stable build of vscode - same problem there as well.

Reproduce the issue with test.java and the provided launch.json, setting breakpoints on lines 4 and 10 and stepping over the lambda. Compare the observed entry into HashMap.class with the expected step-filter behavior; done means stepping over the lambda and avoiding standard-library classes as configured.
