SA-JDI: ReferenceType.nestedTypes() returns unexpected anonymous type

Name: ipR10196 Date: 04/12/2004


-----------------------------------------------------
Test : nsk/sajdi/ReferenceType/nestedTypes/nestedtypes001
VM : ServerVM (either 32-bit and 64-bit)
Mode : -Xcomp
Platform : sparc, sparcv9, x86
OS : SunOs 5.8
JDK : 1.5.0-beta2-b46
------------------------------------------------------

With SA-JDI connectors ReferenceType.nestedTypes() returns unexpected
(not synthetic!) anonymous type:

    type #20
      type name: nsk.sajdi.ReferenceType.nestedTypes.nestedtypes001aTestedClass$1
      signature: Lnsk/sajdi/ReferenceType/nestedTypes/nestedtypes001aTestedClass$1;
      generic: null
      modifiers: 0x28
      isPublic: false
      isPrivate: false
      isProtected: false
      isPkgPrivate: true
      isAbstract: false
      isFinal: false
      isStatic: true
      isPrepared: false
      isVerified: false
      isInitialized:false
      failedToInit: false
      isInterface: false
      isSynthetic: false
      VM mirror: JVM version 1.5.0-beta2 (Java HotSpot(TM) Server VM, compiled mode)
      toString: class nsk.sajdi.ReferenceType.nestedTypes.nestedtypes001aTestedClass$1
                    (loaded by instance of sun.misc.Launcher$AppClassLoader(id=0))

  # ERROR: ReferenceType.nestedTypes() returned unexpected type:
  # ERROR: type nom: 20
  # ERROR: type name: nsk.sajdi.ReferenceType.nestedTypes.nestedtypes001aTestedClass$1
  # ERROR: signature: Lnsk/sajdi/ReferenceType/nestedTypes/nestedtypes001aTestedClass$1;
  # ERROR: isSynthetic: false

This happens only on Solaris/sparc and Solaris/x86 platforms with
ServerVM in -Xcomp mode. In all other modes nestedTypes() never
returns any anonymous types.

With legacy JDI connectors nestedTypes() also never returns any
anonymous types in all modes.

This bug may be triggered by recent javac changes in b46.
Compiled with javac from b45 this anonymous type have synthetic flag:

    type #24
      type name: nsk.sajdi.ReferenceType.nestedTypes.nestedtypes001aTestedClass$1
      signature: Lnsk/sajdi/ReferenceType/nestedTypes/nestedtypes001aTestedClass$1;

      isStatic: true
      isPrepared: false
      isVerified: false

  # WARNING: ReferenceType.fields() returned synthetic type:

To reproduce this failure:
  cd /net/jano.sfbay/export/disk20/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME
  sh run.sh [-pid | -core | -socket] [-g] [-v] $JAVA_HOME [JAVA_OPTS]
where:
    -pid - run test with SA-JDI pid attaching connector (default)
    -core - run test with SA-JDI core attaching connector
    -socket - run test with JDI socket attaching connector
    -g - run test with java_g binaries
    -v - run test in verbose mode
