Strange JDK problem

[Vasile GABURICI <ga...@cs.pub.ro>]

	Hi all,

	I have encountered a weird problem while compiling jsps that use
taglibs. I've solved it, but I thought that others might run into this
too, so here it goes: 

	I was using the ftp://ftp.falsehope.com/home/gomez/jakarta/3.1/
RPMs and Sun's JDK1.2.2. While testing the taglib example that comes with
tomcat I've always got this stack trace: 

java.lang.IllegalAccessError: try to access class
com/sun/xml/tree/ParentNode from class

	For some odd reason the problem went away when using IBM JDK
1.1.8. This was the same JDK that was used by Gomez Henri to make the
rpms.

	So, I though that it has something to do with JDK versions,
although in theory there should not be such issues! Thus I rebuilt the rpms
with JDK 1.2.2 and the problem went away for good.

	I presume that IBM did not tinker with the compiler in the 1.1.8
JDK, so this could be categorized as a bug in JDK 1.1.8 compiler.

	If anybody can reproduce this, please let me know...
