UnsatisfiedLinkError on using API from javabuilder.jar

Postby vallabh.anwikar » Mon Apr 18, 2016 12:27 pm

Hi All,

I am trying to use YourKit for profiling my code which uses data structures form javabuilder.jar which is given by Matlab. Its used for java and matlab integration. I am getting following error during profiling error. How can we specify such libraries ?
Can we bypass such code which can't be handled by Profiler treat it like black box ? meaning not instrumenting such code at all and just measure timing properties of such functions ?

java.lang.UnsatisfiedLinkError: while attempting to locate symbol Java_com_mathworks_toolbox_javabuilder_internal_MWMCR_$$YJP$$mclAddCanonicalPathMacro: /usr/local/MATLAB/MATLAB_Compiler_Runtime/v717/bin/glnxa64/libnativemcl.so: undefined symbol: Java_com_mathworks_toolbox_javabuilder_internal_MWMCR_$$YJP$$mclAddCanonicalPathMacro
com.mathworks.toolbox.javabuilder.internal.DynamicLibraryUtils.$$YJP$$dlsym(Native Method)

Thanks and Regards,

Hi Vallabh

Perhaps Matlab uses a class loader that does not correctly work with instrumented native methods.

Please specify the agent startup option "disablenatives".
How to do this: https://www.yourkit.com/docs/java/help/ ... ptions.jsp
