Call service via REST API fail

[GuBin1373]

Hi,
I created a sideview in Oxygen using the sdk. When I attempted to load some data to Jpanel component via rest api ,errors such as the following occurred:
(1)

Hi,
That's strange, can you paste more details from the stack traces, ideally the entire stack traces?
You are running Oxygen using its executable or oxygen.bat startup script, right?
Regards,
Radu

Hi,
Below are the complete stack traces.
I have tried running both executable file and oxygen.bat startup script ,but none of them affect the result.
My code is located in the "com.zony" package.

Hi,

If you are using "java.util.concurrent.ForkJoinPool.commonPool()" in your code, please avoid this as this common pool is initialized very early without taking our security manager into account. Please create and keep static somewhere your own ForkJoinPool instance, then use it in your code.

Radu
