java.lang.NoSuchMethodError: org.bouncycastle.math.ec.ECCurve$Fp – Issue

In this post, I will discuss one tip everyone can use to avoid bouncy castle error.

Problem

Recently I was working on building a SOAP webservice where we were using Apache CXF libraries along with Spring boot. We built the webservice, but when we were sending a SOAP request through the client, we kept getting following error:

A Simple tip to avoid this error –

We tried different things to resolve this issue. We tried to exclude bouncycastle jars from cxf-rt-ws-security dependencies we were using as we were pulling them from other dependencies. But this error would still pop up intermittently. Eventually, I figured out the issue. We had to add this dependency of bouncycastle explicitly as below in our Gradle build file. That’s when the error went away.

compile (‘org.bouncycastle:bcprov-jdk15on:1.56’) 

Conclusion

In this post, I showed how to use this one tip to avoid the error caused by the bouncy castle. If you enjoyed this post, subscribe to my blog here.
