java - `JCE cannot authenticate the provider BC` when running a JAR -

-

in scala project use "org.bouncycastle" % "bcprov-jdk14" % "1.51" cryptography.
if test project in scala ide works fine. once make jar , try run via java -jar ... throws exception: exception in thread "main" java.lang.securityexception: jce cannot authenticate provider bc

i use https://github.com/sbt/sbt-assembly making jar , here's java -version output: 

java version "1.7.0_72" java(tm) se runtime environment (build 1.7.0_72-b14) java hotspot(tm) server vm (build 24.72-b04, mixed mode)

when making jar see output: 

[info] merging files... [warn] merging 'meta-inf/bckey.dsa' strategy 'discard' [warn] merging 'meta-inf/bckey.sf' strategy 'discard' [warn] merging 'meta-inf/lambdawo.sf' strategy 'discard' [warn] merging 'meta-inf/manifest.mf' strategy 'discard' [warn] merging 'reference.conf' strategy 'concat' [warn] merging 'rootdoc.txt' strategy 'concat' [warn] strategy 'concat' applied 2 files [warn] strategy 'discard' applied 4 files

how can fix issue?

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11...
