On our production server, this causes either one of these exceptions to appear
every few days or weeks.
The same test in issue GROOVY-2105 causes the problem on Linux again. I double
checked the fix that was implemented for this ticket, and the fix (adding
synchronized to 3 methods) was removed in a later refactor of
GroovyCategorySupport.
I will attach 3 test cases that reproduce the threading issue. The problem
does not happen 100% of the time, you may have to play with the number of
threads to generate the exception.
