Error trying to run tomcat hello server #537

Open AntonBikineev opened 7 years ago

AntonBikineev commented 7 years ago

Hi, I've run into an error trying to run tomcat under avian-openjdk. The error is stackoverflow and it seems it is caused by a recursive call to ClassLoader.definePackage:

Exception

javax.servlet.ServletException: java.lang.StackOverflowError
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:338)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:742)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53)
Root Cause

java.lang.StackOverflowError

    java.lang.ClassLoader.definePackage(Unknown Source)
    avian.SystemClassLoader.getPackage(Unknown Source)
    java.lang.ClassLoader.definePackage(Unknown Source)
...

Does anybody know why this happens? The command to run jvm is as follows:

~/git/avian-openjdk/build/linux-x86_64-openjdk-src/avian -cp bin/bootstrap.jar:bin/tomcat-juli.jar:lib/annotations-api.jar:lib/catalina-ant.jar:lib/catalina-ha.jar:lib/catalina.jar:lib/catalina-storeconfig.jar:lib/catalina-tribes.jar:lib/ecj-4.6.3.jar:lib/el-api.jar:lib/jasper-el.jar:lib/jasper.jar:lib/jaspic-api.jar:lib/jsp-api.jar:lib/servlet-api.jar:lib/tomcat-api.jar:lib/tomcat-coyote.jar:lib/tomcat-dbcp.jar:lib/tomcat-i18n-es.jar:lib/tomcat-jdbc.jar:lib/tomcat-jni.jar:lib/tomcat-util.jar:lib/tomcat-util-scan.jar:lib/tomcat-websocket.jar:lib/websocket-api.jar org.apache.catalina.startup.Bootstrap start

I've enumerated all jars in the classpath option because it seems like avian doesn't support wildcards yet.

Hi Anton,

That looks like a bug; thanks for reporting it. I'll investigate it this weekend when I have time.

Would you please give this a try when you have a chance?

It's been a long time since I tried to run Tomcat with Avian, so there may be other issues besides this one. I'm currently running low on disk space on my laptop, so I can't test Tomcat myself right now, but the above PR should fix the StackOverflowError, at least.

Hi Joel, Yeah, your patch fixes the problem! And the simple tomcat application runs fine. However, I've noticed a couple of other problems: 1) There is no log in stdout/stderr that I can observe; 2) I can run tomcat under hotspot using the following command line:

java -cp bin/bootstrap.jar:bin/tomcat-juli.jar org.apache.catalina.startup.Bootstrap start

I don't understand how hotspot recognizes that it needs to load jars from the lib directory (I couldn't find corresponding "Class-Path" lines in manifest files). If I run avian using the same arguments, it just returns with 0 error code. 3) With hotspot I can specify wildcards in '-cp' argument, whereas avian again returns with 0 return code. It also seems to speed up class loading in hotspot. So the only way I found to run tomcat using avian is by specifying all jars in command line, e.g.:

 ~/git/avian-openjdk-2/build/linux-x86_64-openjdk-src/avian -cp bin/bootstrap.jar:bin/tomcat-juli.jar:lib/annotations-api.jar:lib/catalina-ant.jar:lib/catalina-ha.jar:lib/catalina.jar:lib/catalina-storeconfig.jar:lib/catalina-tribes.jar:lib/ecj-4.6.3.jar:lib/el-api.jar:lib/jasper-el.jar:lib/jasper.jar:lib/jaspic-api.jar:lib/jsp-api.jar:lib/servlet-api.jar:lib/tomcat-api.jar:lib/tomcat-coyote.jar:lib/tomcat-dbcp.jar:lib/tomcat-i18n-es.jar:lib/tomcat-jdbc.jar:lib/tomcat-jni.jar:lib/tomcat-util.jar:lib/tomcat-util-scan.jar:lib/tomcat-websocket.jar:lib/websocket-api.jar org.apache.catalina.startup.Bootstrap start

I just downloaded Tomcat 9 and tried running it with Avian. The output is at the end of this post.

It looks like there are several problems, the most serious of which is that the VM seems to be aborting due to an assertion failure when handling a lambda expression. That's not a big surprise, since lambdas are still a work in progress on Avian, as you can see in https://github.com/ReadyTalk/avian/pull/539.

I'm not sure why you're not getting any stdout/stderr output, though. Which version of Tomcat are you using?

I'll look more closely at this when I have time this weekend.

Tomcat 9 is working for me as of this commit: https://github.com/ReadyTalk/avian/commit/a329416f4f37840d2a5d7976874585413cd4c6af

I run it like this:

Please let me know if you're still having trouble with the latest code.
