Hi,

1.5.2 doesn't build on Jessie and Trusty anymore (JDK 7):

https://pgdgbuild.dus.dg-i.net/job/postgresql-pljava-binaries/24/
https://pgdgbuild.dus.dg-i.net/job/postgresql-pljava-binaries/24/architecture=amd64,distribution=jessie/console

23:35:43 [ERROR] /<<PKGBUILDDIR>>/pljava-examples/src/main/java/org/postgresql/pljava/example/saxon/S9.java:[35,16] error: package java.time does not exist
23:35:43 [ERROR] /<<PKGBUILDDIR>>/pljava-examples/src/main/java/org/postgresql/pljava/example/saxon/S9.java:[879,12] error: cannot find symbol
23:35:43 [ERROR] symbol: variable TIME_WITH_TIMEZONE
23:35:43 [ERROR] location: class Types

(There is another issue that apparently maven doesn't like running
several times in parallel, it chokes while reading/writing to ~/.m2.)

I've also enabled -Psaxon-examples - is it correct that no new files
appear in the .deb, but the examples are inside the existing
/usr/share/postgresql/11/pljava/pljava-examples-1.5.2.jar file?
