A DESCRIPTION OF THE PROBLEM :
The source file compiler.properties contains the English message bundle for compiler warnings, errors, etc.

Since the strings in this file are format strings, any single quotes must be escaped by doubling them.

An example of a properly encoded entry is:

compiler.err.cant.assign.val.to.this=\
    cannot assign to ''this''

There are three entries that appear to be not escaped when they should be. These are:

compiler.err.dc.no.tag.name=\
   no tag name after '@'

compiler.warn.leaks.not.accessible.not.required.transitive=\
   {0} {1} in module {2} is not indirectly exported using 'requires transitive'

compiler.err.cant.inherit.from.sealed=\
    class is not allowed to extend sealed class: {0} \
    (as it is not listed in its 'permits' clause)

The (fairly harmless) result is that the single quote marks are missing from the compiler output.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Generate any of the warnings or errors and notice they are missing single quote marks.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
B.java:1: error: class is not allowed to extend sealed class: A (as it is not listed in its 'permits' clause)

ACTUAL -
B.java:1: error: class is not allowed to extend sealed class: A (as it is not listed in its permits clause)


---------- BEGIN SOURCE ----------
$ cat > A.java
public sealed class A {
}

$ cat > B.java
public class B extends A {
}

$ javac A.java B.java
A.java:1: error: sealed class must have subclasses
public sealed class A {
              ^
B.java:1: error: class is not allowed to extend sealed class: A (as it is not listed in its permits clause)
public class B extends A {
       ^
2 errors
