Do you get an hs_err file when the failure happens? If so then a stack trace at the point of crash might well help pin down where the problem lies.

aah, No I don't get any hs_err file. I looked into `build/linux-s390x-server-fastdebug/make-support/failure-logs` directory and only thing I could I find is last command it ran. 

 /home/amit/jdk/build/linux-s390x-server-fastdebug/jdk/bin/javac -J-Djava.io.tmpdir=/home/amit/jdk/build/linux-s390x-server-fastdebug/support/javatmp -g -Xlint:all -source 24 -target 24 -implicit:none -Xprefer:source -XDignore.symbol.file=true -encoding ascii -Werror --add-modules jdk.compiler,jdk.jdeps --add-exports jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED --add-exports jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED --add-exports jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED --add-exports jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED --add-exports jdk.jdeps/com.sun.tools.classfile=ALL-UNNAMED -Xlint:-options -XDmodifiedInputs=/home/amit/jdk/build/linux-s390x-server-fastdebug/buildtools/create_symbols_javac/_the.COMPILE_CREATE_SYMBOLS_batch.modfiles.fixed -d /home/amit/jdk/build/linux-s390x-server-fastdebug/buildtools/create_symbols_javac @/home/amit/jdk/build/linux-s390x-server-fastdebug/buildtools/create_symbols_javac/_the.COMPILE_CREATE_SYMBOLS_batch.filelist 


After running I get:
