Description Pavel Flaska 2004-05-27 15:08:19 UTC 
I tried to scan rt.jar from JDK 1.5 in our
refactoring build to create name index. I have got
the IOExceptions.

Comment 2 Pavel Flaska 2004-05-27 15:13:48 UTC 
I did some observation and seems that the problem is in Annotation
class. Seems that original exception is CCE:

java.lang.ClassCastException: org.netbeans.modules.classfile.CPUTF8Info

Comment 3 _ tball 2004-05-27 16:27:51 UTC 
Problem is due to error when loading an annotation type that defines
an array of possible values, such as
java.lang.annotation.RetentionType.  Fix in progress...

*** Issue 43933 has been marked as a duplicate of this issue. ***
Comment 5 Tomas Hurka 2004-05-27 16:35:40 UTC 
Priority changed to P1, since duplicated issue #43933 is P1.
Comment 6 _ tball 2004-05-27 17:09:28 UTC 
Fixed loading of annotations with array element values.
Comment 7 Jan Pokorsky 2004-05-27 17:53:19 UTC 
Still broken -> reopened.

Comment 9 Pavel Flaska 2004-05-27 18:52:03 UTC 
I saw the name java.lang.annotation.Inherited when I met the CCE in
Annotation.java.
Comment 10 _ tball 2004-05-27 23:58:10 UTC 
The JDK 1.5 beta 1 had classfiles in its jce.jar file with corrupted
EnclosingMethod attributes.  This may have been due to that jar file
being obscurated with DashO, or a compiler bug since fixed.  In any
event, the classfile module now recovers more gracefully from these
bad files.  I am able to bring up the latest build using JDK 1.4.2,
1.5 beta 1, and 1.5 build 49.
Comment 11 psuk 2004-05-28 09:30:38 UTC 
Reopening.
Doesn't work on J2SE 1.5 Beta 2.
Is the bug filed against JDK?
Comment 12 Pavel Flaska 2004-05-28 09:36:41 UTC 
Reproducible with jdk1.5.0-b51, jdk1.5.0-b51a.
Cannot reproduce with jdk1.5.0-b49 and jdk1.5.0-b50.
Comment 13 _ tball 2004-05-28 17:14:39 UTC 
It appears that the classfile format has again changed as of build 51:
 annotation types are now a UTF8 instead of a Class constant pool
entry.  The annotation attribute loader now tests for both types and
loads appropriately for that type.
Comment 14 Martin Matula 2004-05-28 18:27:17 UTC 
Verified with JDK 1.5 build 49 and 51 (beta 2).
