    Hi,

     

    do you have any idea how to solve the next error, that we got after upgrading APM to APM10.5.1 and trying to start ATC/WV.

     

    we get the next error message in ATC/WV in the browser:

     

     

    and the next error logs in WV.log file:

    Hi Stefan:

      Googling this error, it occurs on other products as well. It appears to be related to Java release.(especially 1.8) Please see if an earlier supported Java release helps remedy the situation. You can also ask on teh internal forums as well.

     

    Thanks

    https://issues.apache.org/jira/browse/AMQ-5356 

    It does seem so per this link and other ones...specific to Java 1.8 and seemingly not affecting Java 1.7.

    Hi Francis, Hal,

    we've tried JDK1.7 and 1.8 as well, but unfortunately both had the same result = error described above.

    would you have any other recommendation?

    thank you, stefan

    Hi Stefan,

     

    Would you please take the following steps?

    1 - stop the EM / WV servers
    2 - delete the contents of the work directory.
    3 - delete the folders in the following directories (please do NOT delete the config.ini)

    product\webview\configuration

    product\enterprisemanager\configuration
    product\workstation\configuration
    please do NOT delete the config.ini
    4 - Start the EM / WV servers

    Hi, just in case anybody else makes the same typo as we did, then FYI our root cause was the missing -Dorg.osgi.framework.bootdelegation=org.apache.xpath from the java arguments in the Introscope_WebView.lax file. we accidentally removed it while increasing the heapsize there.

     

    this is the incorrect version that we had

    lax.nl.java.option.additional=-Xms4096m -Xmx6144m -Djava.awt.headless=true -Dorg.owasp.esapi.resources=./config/esapi -Dsun.java2d.noddraw=true -XX:PermSize=128m -XX:MaxPermSize=256m

     

    and this is the the correct version:

    lax.nl.java.option.additional=-Xms4096m -Xmx6144m -Djava.awt.headless=true -Dorg.owasp.esapi.resources=./config/esapi -Dsun.java2d.noddraw=true -Dorg.osgi.framework.bootdelegation=org.apache.xpath -XX:PermSize=128m -XX:MaxPermSize=256m

     

    after adding it back, everything works fine.
