Re: [Laszlo-dev] org.openlaszlo.sc.CompilerError: tunit/line, unknown: , in line: Error: PermGen space

[André Bargull]

The compiler also (ab)uses String#intern(), and interned strings are 
stored in the PermGen, too. For example every ASTIdentifier's name is 
interned....

It is definitely the case that Tomcat slowly fills PermGen on each 
undeploy/deploy.  It's a longstanding problem that has to do with classloaders, 
as I recall.  The solution is to restart Tomcat.
