Troubleshooting: Java method transport

You can use workarounds to common problems that you might encounter when you use the Java™ method transport of IBM® DevOps Test Integrations and APIs (Test Integrations and APIs).

  • When you start a Java application into which the Java virtualization agent is installed, VerifyError messages, such as the following example, might be displayed.

    Exception in thread "main" java.lang.VerifyError: JVMVRFY012 stack shape inconsistent; class=com/ibm/crypto/provider/IBMJCE, method=<clinit>()V, pc=308 at java.lang.J9VMInternals.verifyImpl(Native Method)

    Complete the following steps:
    1. Open the Logical View of the Architecture School perspective.
    2. Double-click the relevant logical Java application resource. The Java application window is displayed.
    3. Click the Recording Studio tab.
    4. Under Filter, add a filter to exclude the referenced class. If this problem persists, send a reproducible example to IBM Support.
  • If you are unable to record Java methods by using the Java Agent, detailed troubleshooting instructions are available in the following technote:
