IllegalAccessError initializing ehcache.CacheManager

[masonoise]

I'm wondering if anyone else has run into this problem; some searching showed similar reports using other JBoss products, but nothing quite the same as what I'm seeing. This may or may not actually be a Hibernate issue, but I thought folks in this forum would be most likely to have run into this.

I did a new install of JBoss server 4.0.4.GA with the ejb3 option, on a new Intel MacBook running Mac OS X 10.4.6. JBoss itself runs fine; the problem occurs running the app I'm working on. However, I need to mention that after installation I discovered that for some reason the ehcache jar wasn't installed. I grabbed one from another installation I had and dropped it into /server/default/lib.

I deployed my app, and when it tries to do the first Hibernate-related call I get an IllegalAccessError trying to run ehcache.CacheManager.init(). It is possible that JBossAS 4.0.4.GA needs a newer version of ehcache, I suppose, but since that jar file wasn't put in the lib directory when I installed the server, I can't be sure which version it might be expecting.

Has anyone else encountered this or had similar installation issues? Thanks in advance for any ideas or advice.

Did you find a solution to this? I am having the same issue on a vanilla installation of the jBoss 4.0.4.GA and a vanilla build of jbpm 3.0.3.

Let me know...thanks!

Brad

I have similar problem on 4.0.4-GA (windows)

[masonoise]

I didn't find any solution for this, unfortunately. I was able instead to clone an existing JBoss installation we had which was working, since I couldn't take the time to continue trying to debug this problem. I would still like to know what it was and how to fix it, though...

[blankema]

I am having the same problems. I am very interested in a solution.

Does anyone know how to work around this?

[nathanmeyers]

I'm hitting the same problem. The line of code causing the problem is:

manager = new CacheManager();

in EhCacheProvider... in the version of EHCache I've been using, CacheManager's constructors are private. In the EHCache lib found in Hibernate's 3.2 source tree (ehcache-1.2.jar), the constructors are public. So, assuming it doesn't break anything to move to that ehcache release, the fix is to move to that ehcache release.

Hi

Anybody found a resolution to this?

I'm running 4.0.3 fine but the moment I go to 4.0.4GA I get this problem?

Tks

Try upgrading to ehcache 1.2.

http://jira.jboss.com/jira/browse/JBAS-3209

[laxman]

Hurry. the problem is solved.

Please download ehcache1-2.zip from

http://www.ibiblio.org/maven2/net/sf/ehcache/ehcache/1.2/

rename zip to jar and put it in classpath. It works.

Thanks for the above post.

In the jbpm context (jbpm 3.1.2 from the starter kit on top of JBOSS 4.0.4 GA), here's what we did to fix things (from our internal wiki):

The JBPM application included in the starters kit includes a version of ehcache, ehcache-1.1.jar, which is out of date and incompatible with the rest of the JBOSS environment.

This link describes a fix to the problem, which is to replace ehcache-1.1.jar with ehcache-1.2.jar.

I did this in the following manner:

$ cd ${JBPM_SRC}/lib/hibernate
$ cp ${DOWNLOADS}/ehcache-1.2.jar .
$ svn rm ehcache-1.1.jar
$ svn add ehcache-1.2.jar

We also need to edit ${JBPM_SRC}/build.xml and change the reference to ehcache-1.1.jar to ehcache-1.2.jar, so that the new jar file is properly included in the jbpm.sar file that results.

After this was done, I just rebuilt and re-installed the application. See below for the details.

I had the same problem, using hibernate 3.1.3 without MBean.

the problem is that JBoss 4.0.4 has hibernate 3.2 installed.
and this version should use ehcache-1.2

to fix this, just remove hibernate from the lib. maybe cglib too(I removed it).
