-----------------------------------
Assignee: (was: Eric Milles)
> Cannot access protected field of Java superclass with --illegal-access=deny
> ---------------------------------------------------------------------------
>
> Key: GROOVY-9596
> URL: https://issues.apache.org/jira/browse/GROOVY-9596
> Project: Groovy
> Issue Type: Bug
> Components: bytecode
> Affects Versions: 3.0.4, 2.5.12
> Environment: JDK 14
> Groovy 2.5.12 or 3.0.4
> Reporter: Kevin Rushforth
> Priority: Major
> Attachments: Main.groovy, Main2.groovy, MyAWTEvent.groovy,
> MyFilterReader.groovy
>
>
> When using the Java option {{--illegal-access=deny}}, a Groovy subclass that
> extends a Java superclass in the Java runtime (e.g., a class in the
> {{java.base}} module) cannot access a protected field in the parent class
> using {{this.fieldName}}.
> To reproduce this bug, use JDK 14 (or later) and run the following using
> either Groovy 2.5.12 or 3.0.4:
> {{$ groovyc Main.groovy MyFilterReader.groovy}}
> {{$ _JAVA_OPTIONS="--illegal-access=deny" groovy Main}}
> It works correctly without {{--illegal-access=deny}}. You can add
> {{-Dsun.reflect.debugModuleAccessChecks=access}} to get more detailed
> information about the illegal access exceptions that are being swallowed by
> Groovy.
> {{$ _JAVA_OPTIONS="--illegal-access=deny
> -Dsun.reflect.debugModuleAccessChecks=access" groovy Main}}
> WORKAROUND: change the following line in the Groovy subclass:
> line = ((BufferedReader)this.in).readLine();
> to:
> line = ((BufferedReader)super.in).readLine();
