[Geoserver-devel] WMS and label rendering problem

hannes.scharmann@anonymised.com reported this problem. See the message
below ("[Geoserver-users] TextSymbolizer - JavaVM SIGSEGV").
checktronik@anonymised.com also found the problem.

checktronik reported it happening in java 1.4 and 1.5. Have you tried
with jetty (ie. is this a tomcat thing)?

Looks like you're going to have to talk to Sun, unless the call to the
Font metrics in:
org.geotools.renderer.lite.LabelCacheDefault.overlappingItems(Ljava/awt/font/GlyphVector;Ljava/awt/geom/AffineTransform;Ljava/util/List;)Z+45
is being called "funny".

Even so, you should not be able to crash the VM. Is it near memory
limit?

--------------------

we encounter a problem with geoserver 1.30rc2:
while requesting a map with multiple layers (the street featuretype's
style is using a TextSymbolizer) using wms the java vm crashes with
following error:

#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# SIGSEGV (0xb) at pc=0x49d403f2, pid=28661, tid=1221217200
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_03-b07 mixed mode, sharing)
# Problematic frame:
# C [libfontmanager.so+0x463f2]
Java_sun_font_FileFont_getGlyphImage+0x174
#

layer definition rule for our street featuretype looks like this:
<TextSymbolizer>
       <Label>
               <ogc:PropertyName>ROUTENUM</ogc:PropertyName>
       </Label>
       <Font>
               <CssParameter name="font-family">Courier</CssParameter>
               <CssParameter name="font-style">bold</CssParameter>
               <CssParameter name="font-size">12</CssParameter>
               <CssParameter name="font-color">#000000</CssParameter>
       </Font>
</TextSymbolizer>
