Created attachment 1724 javaws log

            We are trying to run SAP PI Development tools (Directory and Repository) and they fail with
            LAZY_CLASSLOADING_FAILED

            Application is SAP Netweaver Enterprise Services Builder 7.31

            Windows 10

            I have tried IcedTeaWeb with:

            Oracle Java JDK 8u201 (64 Bit)
            Azul Zulu Java 8u201 (64 and 32 Bit)
            Azul Zulu Java 7u201 (64 Bit)

            Cheers

            Chris

Hmm. That is already thrown from application space. Can I debug it somewhere? Can you narrow the reproducer? Otherwise the only hope for you is to debug ITW itself (which is not hard).

Hi Team,

when this bug happened in Oracle JRE 1.7 it was also raised to SAP support. Here is official statement to this issue:

Cause Bug on the Oracle side - see JDK-8017776 : Swing Event Thread does not use JNLP class loader

Resolution Oracle have confirmed that this regression will be fixed in version 1.7.0_40 To workaround this error, it is recommended to use a Java version other than 1.7.0_25. This error does not occur in the 1.7.0_21 version, for example. Other workarounds are mentioned in this SCN thread - JRE 7.25 incompatible with PI Tools

If you need sandbox system for testing/debugging we do have one.

@ccrashh is this issue still open?

Adding https://github.com/AdoptOpenJDK/IcedTea-Web/issues/318 since it is about SAP PI, too. The issue is a different one.
