ArcSDE and Java 7u80

[MarkQuan]

We are using the 64 bit ArcSDE 10.1 SDK Java library using
Direct Connect to an Oracle 11g database. We don’t have any problems with Java
7u79. But with Java 7u80 and beyond including Java 8 the ArcSDE
Java library is freezing instantiating a new SEConnection object. I think I
have narrowed the freezing to sdejavautil.dll inside the gsrvrStartProgram()
method. Has anyone else encountered this issue?

There is a BUG 000087489 about ArcSDE SDK 10.2.2 for Java hangs when connecting to an Oracle database when using JDK8u40+ http://support.esri.com/en/bugs/nimbus/QlVHLTAwMDA4NzQ4OQ== . If it is important to your workflow, it might be better if you log a support case to further look into it.
