Description
Compiling reg test InterfaceInInner.java

class InterfaceInInner {
    InterfaceInInner() {
        class foo {
            interface A {
            }
        }
    }
}

fails as expected but as of nightly build of 1/25/11 returns 4 instead of 1.
This other reg tests which failed like this are
AnonStaticMember_2.java and QualifiedNew.java

SUGGESTED FIX A webrev of this fix is available at the following URL: http://hg.openjdk.java.net/jdk7/tl/langtools/rev/afe226180744

EVALUATION The different exit code indicates a javac crash, which is bad.
26-01-2011
EVALUATION Under some circumstances, javac will silently swallow a crash, especially after error messages have been generated. That may be what is happening here. See Main.java:448. } catch (Throwable ex) { // Nasty. If we've already reported an error, compensate // for buggy compiler error recovery by swallowing thrown // exceptions. if (comp == null || comp.errorCount() == 0 || options == null || options.isSet("dev")) bugMessage(ex); return EXIT_ABNORMAL;

EVALUATION InterfaceInInner.java appears to have same results other than return code. QualifiedNew.java yields only 1 error instead of 2 in addition to the return code.This would hint at the crash. AnonStaticMember_2.java crashes whereas before it did not: g:\ws\7\tools\src\javac\devregtests]javac AnonStaticMember_2.java An exception has occurred in the compiler (1.7.0-ea).

EVALUATION For the record, here are the javac exit codes: static final int EXIT_OK = 0, // Compilation completed with no errors. EXIT_ERROR = 1, // Completed but reported errors. EXIT_CMDERR = 2, // Bad command-line arguments EXIT_SYSERR = 3, // System error or resource exhaustion. EXIT_ABNORMAL = 4; // Compiler terminated abnormally so the bug is not really that javac is returning different error codes -- it would appear to be crashing.
