Subject PropertyDescriptor: internal error while merging PDs: with jdk1.4
Date Sat, 07 Feb 2004 04:03:17 GMT
Greetings,

I get the following error when I run a web app with:


java version "1.4.2_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_01-b06)
Java HotSpot(TM) Client VM (build 1.4.2_01-b06, mixed mode)

It works without any problems with:

java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

OS: Win XP professional.
Server: Resin 2.1.4


Thank you,
--a
