Description
javac in jdk1.5 throws exception while compiling. The same source code is compiled successfully with Tiger b49.

EVALUATION The compiler might have changed behavior and the compiler crashes. However, this is a matter of a class missing from the build: weblogic\qa\tests\interop\ejb11\basic\stateful\TraderHome.class The file tst/weblogic/dev/tools/interop/classes/weblogic/qa/tests/interop/ejb11/basic/BaseSessionBeanTest.class refers to that class: [ahe@newman 6180021]$ javap -verbose tst/weblogic/dev/tools/interop/classes/weblogic/qa/tests/interop/ejb11/basic/BaseSessionBeanTest | grep Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome\; const #45 = Asciz (Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome;)Ljavax/ejb/EJBObject;; const #47 = Asciz Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome;; 0 16 1 home Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome; 15 7 2 home Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome; 14 12 2 home Lweblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome; [ahe@newman 6180021]$ Since the compiler crashes, I'm proposing a fix that would give this error message: tst/weblogic/dev/tools/interop/src/weblogic/qa/tests/interop/ejb11/txcrossdomain/TxCrossDomainTest.java:13: problem during type translation; file weblogic/qa/tests/interop/ejb11/basic/stateful/TraderHome.class not found missing symbol: weblogic.qa.tests.interop.ejb11.basic.stateful.TraderHome from method : createBean(weblogic.qa.tests.interop.ejb11.basic.stateful.TraderHome) in : weblogic.qa.tests.interop.ejb11.basic.BaseSessionBeanTest public class TxCrossDomainTest extends BaseSessionBeanTest { ^ I'm very interested in feedback on the usefulness of this error message. ###@###.### 10/16/04 03:08 GMT I have investigated a bit further and this was apparently caused by the fix for 5041233. I have discovered a way to revert to the behavior of tiger b49. However, I do not intend to apply that fix since it will become obsolete after 5034571 is fixed. I really think that the right solution is to include TraderHome.class in the build. ###@###.### 10/16/04 04:35 GMT We are currently working on integrating the workaround as 5034571 is not suitable for backporting to a Tiger update. ###@###.### 2005-03-30 20:42:13 GMT Producing good regression tests complicated the fix. However, we have regression tests now and the fix is targeted for Mustang and Tiger update 6. ###@###.### 2005-06-08 22:09:10 GMT The fix is targeted JDK 5.0 update 5. ###@###.### 2005-06-14 20:27:07 GMT
