Servlet 3.0 Specific Error: Invalid byte tag in constant pool
Hey guys,
tomcat 7.0.19
Java 1.6.0_22
CentOS 5.6
I just switched the web.xml to servlet 3.0 (from a app running servlet 2.4
previously without issue) and now I'm seeing the following error (turned on
fine logging in the util class):
FINE: Scanning JAR [file:/usr/java/jdk1.6.0_22/jre/lib/ext/jcharset.jar]
from classpath
Jul 19, 2011 10:04:40 AM org.apache.catalina.startup.HostConfig
deployDirectory
SEVERE: Error deploying web application directory ROOT
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag
in constant pool: 60
Thanks,
Matt

Konstantin,
I may have to give the debugger a try - thanks for the info.

The above message is created by
o.a.tomcat.util.bcel.classfile.Constant#readConstant(...). There is a
switch() and default: label results in this exception being thrown.
Expected values there are from 1 to 12. Your 60 is far outside the
range.

I hoped to see some information about what class files in those jars
BCEL tries to scan when it fails.
Call hierarchy is
bcel.classfile.Constant#readConstant(...)
<- bcel.classfile.ConstantPool#ConstantPool(stream)
<- bcel.classfile.ClassParser#readConstantPool()
<- bcel.classfile.parse()
<- o.a.catalina.startup.ContextConfig#processAnnotationsStream(stream, webxml)
Unfortunately there is no debug printing in ContextConfig, and
ClassParser operates on a stream and so does not know its context.
Maybe you can run your copy of Tomcat with debugger, using remote debugging?

Are you sure that is the version of Java that Tomcat is starting with?

java -version:
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)
We just upgraded it from 1.6.0_22 to see if it would address this problem
(it didn't).

Did that - its actually how I got the name of the files failing.
Thanks for taking a look.

Adding that to the skip list definitely prevented that error, but I'm
getting many jars with the same problem. I thought I could maybe get away
with just skipping them all, but I'm starting to see some jars that have
taglibs in them (and so need to be scanned).
All these jars are giving the same error:
,asm.jar,jboss-cache.jar,backport-util-concurrent.jar,struts-tiles-1.3.5.jar,shared-ldap-0.9.5.5.jar,jniwrap-3.6.jar,org.osgi.core-4.1.0.jar,fontbox-1.6.0.jar,apacheds-server-jndi-1.0.2.jar,apacheds-protocol-ldap-1.0.2.jar,jetm-1.2.2.jar,gdata-contacts-meta-3.0.jar,standard.jar,xbean-spring-2.8.jar,custom_rhino.jar,apacheds-server-ssl-1.0.2.jar,poi-ooxml-schemas-3.8-beta2-20110408.jar,commons-cli-1.2.jar,gdata-contacts-3.0.jar,webservices-rt.jar,iText-2.1.7.jar,javassist-3.9.0.GA.jar,mime-util-2.1.3.jar,jcaptcha-all-1.0-RC3.jar,ical4j-1.0-rc3-SNAPSHOT.jar,tomcat-jdbc.jar,dnsns.jar,jcharset.jar,pager-taglib.jar
Any ideas?
Thanks,
Matt

That might be a BCEL bug or could be a corrupted JAR. Just add it to the
jarsToSkip property in catalina.properties.
Also, if you open a bugzilla issue, someone will take a closer look.
