RFR: 8332287: When printing arguments in error logs, quote arguments with whitespaces

[Thomas Stuefe]

Trivial fix to a simple issue.

In hs-err files, when printing the arguments of the crashed JVM process, print arguments with whitespaces in them with quotes. Makes it easier to copy-paste them to terminals.

Before:

Command Line: -Dtest.vm.opts=-XX:+UnlockDiagnosticVMOptions -XX:-TieredCompilation -XX:+StressArrayCopyMacroNode -XX:+StressLCM -XX:+StressGCM -XX:+StressIGVN -XX:+StressCCP -XX:+StressMacroExpansion -XX:+StressMethodHandleLinkerInlining -XX:+StressCompiledExceptionHandlers -XX:CompileCommand=memlimit,*.*,1G~crash -XX:CompileCommand=memstat,*::*,print -Dtest.tool.vm.opts=-J-XX:+UnlockDiagnosticVMOptions -J-XX:-TieredCompilation -J-XX:+StressArrayCopyMacroNode -J-XX:+StressLCM -J-XX:+StressGCM -J-XX:+StressIGVN -J-XX:+StressCCP -J-XX:+StressMacroExpansion -J-XX:+StressMethodHandleLinkerInlining -J-XX:+StressCompiledExceptionHandlers -J-XX:CompileCommand=memlimit,*.*,1G~crash -J-XX:CompileCommand=memstat,*::*,print -XX:+StressCompiledExceptionHandlers -XX:CompileCommand=memlimit,*.*,1G~crash -XX:CompileCommand=memstat,*::*,print -Djava.library.path=/shared/projects/openjdk/jdk-jdk/output-fastdebug/images/test/hotspot/jtreg/native -Xbatch -XX:CompileCommand=option,*::*,bool,Vectorize,tr

Now (notice the gigantic -Dtest.vm.opts and -Dtest.tool.vm.opts that are actually just one large argument each)


Command Line: "-Dtest.vm.opts=-XX:+UnlockDiagnosticVMOptions -XX:-TieredCompilation -XX:+StressArrayCopyMacroNode -XX:+StressLCM -XX:+StressGCM -XX:+StressIGVN -XX:+StressCCP -XX:+StressMacroExpansion -XX:+StressMethodHandleLinkerInlining -XX:+StressCompiledExceptionHandlers -XX:CompileCommand=memlimit,*.*,1G~crash -XX:CompileCommand=memstat,*::*,print" "-Dtest.tool.vm.opts=-J-XX:+UnlockDiagnosticVMOptions -J-XX:-TieredCompilation -J-XX:+StressArrayCopyMacroNode -J-XX:+StressLCM -J-XX:+StressGCM -J-XX:+StressIGVN -J-XX:+StressCCP -J-XX:+StressMacroExpansion -J-XX:+StressMethodHandleLinkerInlining -J-XX:+StressCompiledExceptionHandlers -J-XX:CompileCommand=memlimit,*.*,1G~crash -J-XX:CompileCommand=memstat,*::*,print" -XX:+StressCompiledExceptionHandlers -XX:CompileCommand=memlimit,*.*,1G~crash -XX:CompileCommand=memstat,*::*,print -Djava.library.path=/shared/projects/openjdk/jdk-jdk/output-fastdebug/images/test/hotspot/jtreg/native -Xbatch -XX:CompileCommand=option,*::*,bool,Vectoriz
