Starting from JDK1.4.0 build 90 Jcov agent run with ec=on (enable workaround for JVMPI bug 4400212)
causes java.util.EmptyStackException when trying to profile a simplest program:

> java -Xrunjcov:ec=on,t=m -cp . HelloWorld
Exception in thread "main" java.util.EmptyStackException
at java.util.Stack.peek(Stack.java:79)
at java.lang.ClassLoader$NativeLibrary.getFromClass(ClassLoader.java:1294)
at java.lang.ClassLoader$NativeLibrary.find(Native Method)

at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:322)


This leads to a loss of coverage info for java/lang/ClassLoader$NativeLibrary inner class,
and changes execution semantics.
