Error in Javac compilation for JSP

[Kudret Güler]

Hi,

This is a Glassfish 4.1.1 build 1 instance. Can you please suggest what may be wrong?

Thank you,

Check you deployment descriptor in your war file for initialization attributes like compilerSourceVM or compilerTargetVM it is also possible that these parameters are set in your default-web.xml in the config directory of your domain.

Thank you! Setting compilerSourceVM and compilerTargetVM to 1.8 in default-web.xml fixed the issue. Any guesses why jspc may have defaulted to 1.5 all of a sudden?

Is it possible that you weren't using any Java6+ features in the JSPs? I think that those Java version warnings appear only in case of compile failure, so probably you were using javac 1.5 even before, but problems appeared only when you started to use more modern syntax.

Also, be aware that Payara Server 171 fixes an annoying issue with precompiled JSPs - https://github.com/payara/Payara/pull/1267

With GlassFish and older versions of Payara Server, the JSP compiler was always using javac 1.5 when precompiliing JSPs at deploy time, even when compilerSourceVM and compilerTargetVM were set to higher versions.

I don't think the jsp file in error is using more features than it did before. I only added a "c:choose" block additionally. Depending on how the war file is deployed (precompilejsp enabled versus not) I got slightly a different version of the error in which some_jsp.java was generated but failed to compile with the same error. Investigating the _jsp.java file I did not see any multi catch blocks or try with resources generated, either.
