Linux: option -Xss<size> leads to unexpected results

Name: asR10013 Date: 05/25/2000



    JDK build 1.3.0beta-b06 does not support option -Xss<size> which
sets Java thread stack size. The following sample output demonstrates
incorrect behavior of jvm.
    Note that such behavior is not observed under Solaris.
