 * @summary converted from VM Testbase nsk/jvmti/GetStackTrace/getstacktr001.
 * VM Testbase keywords: [quick, jpda, jvmti, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test exercises JVMTI function GetStackTrace for the current thread.
 *     The test checks the following:
 *       - if function returns the expected frame of a Java method
 *       - if function returns the expected frame of a JNI method
 *       - if function returns the expected number of expected_frames.
 *     Test verifies stack trace for platform and virtual threads.
 *     Test doesn't check stacktrace of JDK implementation, only checks 1st JDK frame.
 * COMMENTS
 *     Ported from JVMDI.
 *
 * @library /test/lib
 * @compile --enable-preview -source ${jdk.version} GetStackTraceCurrentThreadTest.java
 * @run main/othervm/native --enable-preview -agentlib:GetStackTraceCurrentThreadTest GetStackTraceCurrentThreadTest
