I am experiencing the "GenericSignatureFormatError" exception in production runtime occasionally. When things go smoothly, we have following information in log:
[11/4/15 15:40:01:354 CST] 0000013b SystemOut O [RequestId:240c17e6-b8a5-4c55-a6ff-f923df9fcd11] c.f.s.w.s.SDKControllerAspect[50] incoming request: GET /api/v1/csr/account/0 ? appKey=0

However, the request fails from time to time with same input parameters and leaves the following information in log:

This looks very similar to the bug reported few years ago (https://bugs.eclipse.org/bugs/show_bug.cgi?id=207186), but it is for JDK 1.5.
More environment information is provided as follows:
