Nick Gasson 959f8ed4c1 perf jvmti: Do not report error when missing debug information ... If the Java sources are compiled with -g:none to disable debug information the perf JVMTI plugin reports a lot of errors like: java: GetLineNumberTable failed with JVMTI_ERROR_ABSENT_INFORMATION java: GetLineNumberTable failed with JVMTI_ERROR_ABSENT_INFORMATION java: GetLineNumberTable failed with JVMTI_ERROR_ABSENT_INFORMATION java: GetLineNumberTable failed with JVMTI_ERROR_ABSENT_INFORMATION java: GetLineNumberTable failed with JVMTI_ERROR_ABSENT_INFORMATION Instead if GetLineNumberTable returns JVMTI_ERROR_ABSENT_INFORMATION simply skip emitting line number information for that method. Unlike the previous patch these errors don't affect the jitdump generation, they just generate a lot of noise. Similarly for native methods which also don't have line tables.
