Problem description.

the following tests causes compiler to raise assertion:

lang/PKGS/pkgs057/pkgs05707/pkgs05707.html
lang/PKGS/pkgs057/pkgs05708/pkgs05708.html


For example, running the following command:

Z:/Links/stt/jdk_promotions/JDK6.0/b80/binaries/windows-i586/jdk1.6.0/bin/javac -classpath Z:/Links/stt/jck_promotions/6.0/beta/b21/binaries/JCK-compiler-60/classes Z:/Links/stt/jck_promotions/6.0/beta/b21/binaries/JCK-compiler-60/tests/lang/PKGS/pkgs057/pkgs05707/pkgs05707.java Z:/Links/stt/jck_promotions/6.0/beta/b21/binaries/JCK-compiler-60/tests/lang/PKGS/pkgs057/pkgs05707/pkgs05707a.java
